Verizon iPhone 4 the fruit of four year AT&T-phobe standoff

The Verizon iPhone 4 exists, unofficially for the moment of course, for one reason and one reason only: the existence of, for lack of a better term, AT&T-phobes. While many Americans see the difference between the four major cellular carriers to be fractional enough so as not to care, instead choosing the phone they want and then going with a carrier that offers it, just as many Americans have apparently decided that iPhone or not, they’re not willing to touch AT&T with a ten foot phone pole. If that sentiment weren’t so pervasive, those millions of Verizon customers who say they want the iPhone would have long ago changed carriers by now and been on their way. After all, it’s been nearly four years since the iPhone was first introduced. And after four years, the score stands as such: AT&T haters 1, Apple’s desire for exclusivity zero. As such, the Verizon iPhone 4 is nearly out of the womb.

Verizon customers’ reasons for AT&T phobia range far and wide. Some have had specific nightmare billing or service experiences with the latter in the past. Others live in an area in which AT&T’s signal is weak or slow. And still others are going strictly by reputation, unaware that iPhone users tend to have such high expectations for an Apple product experience that they’re probably bad mouthing AT&T in an outsized fashion. Regardless of their various reasons, Verizon Nation has won the battle. The larger question is whether they’ve won the war, as their insistence on avoiding AT&T and waiting for the iPhone to come to them has meant that they’ve been stuck with a phone they didn’t want since 2007 – no small feat considering the increasing consumer reliance on smartphones. But in any case, their victory in the battle, if no the war, has netted them the prize of a shiny new Verizon iPhone 4 just into th new year. It’s perhaps fitting that even with confirmation that the Verizon iPhone 4 is coming, they still have to wait for it just a bit longer. After all, they ought to be used to waiting by now.

Technology a blessing, a curse for remote island

BEAVER ISLAND, Mich. – Muggs Bass doesn't own a computer. She's pretty much dead set against e-mail. Anyone who calls her home on Michigan's remote Beaver Island should be prepared for a busy signal, if she's on her land-line phone. She has no cell.

"When you don't have it, you don't miss it. That's what I say," says the spunky 70-year-old grandmother, who's as comfortable telling jokes at the local pub as she is attending Mass each morning.

Technology isn't really her thing. So, it's a small miracle when Bass drives, once a month, to her island's rural health center to sit down in front of a wide-screen television. There, she and a handful of other islanders connect by video conference with a similar group in Charlevoix, Mich., a two-hour ferry ride to the south and east.

They chat. They laugh. They cry together.

All of them have, or have had, cancer, Bass included. Hers started with a lump in her breast and has since metastasized to her bones, making her cancer treatable, but incurable, her doctors tell her.

Her own grandmother died of the same disease and went off the island for occasional treatments, as Bass does every few weeks. But that grandmother could hardly have imagined a day when islanders talked openly about their cancer, face-to-face with people in a support group miles away.

It's just one of many ways technology is making this rugged place less remote than it once was and, some would say, more livable for more people.

It also gives islanders hope for new jobs that could attract residents to this island in northern Lake Michigan where the year-round population is about 650 people, give or take a few dozen.

"In the last few years, technology has sprung," says Joe Moore, a retired teacher who's known as one of the geeks on the island who helps keep computers running.

Not that the change has come quickly, or that technology always works perfectly.

That's just how it is on an island where a popular bumper sticker reads "Slow Down! This Ain't The Mainland." It's aimed at anyone who's in too big a hurry, including lead-footed tourists who kick up dust on the many dirt roads or who panic when cell phone service drops.

That's life on wired — or at least, semi-wired — Beaver Island.

___

So, where is Beaver Island, anyway?

Some Michiganders would show you by holding up their right hands, palms up, and pointing just above the tip of their ring fingers — in other words, just off the far northwest tip of the state's lower peninsula. But that's if even THEY know where it is.

While Michigan's Mackinac Island is well known, Beaver Island — much of its 54 square miles covered in lush hardwood forests, sand dunes or pristine inland lakes — is not.

That's partly because it is more difficult to get to, especially in the off season. Ferry service runs from Charlevoix, from April through mid-December. Quick flights in small propeller planes are available year-round, weather permitting. In winter, it's not unusual for islanders to be physically cut off from the mainland, unless an emergency sends the U.S. Coast Guard to their rescue.

So when high-speed Internet service became available to most of the island last spring, this was more than just a convenience. For many, it was a godsend — even if having the service simply meant being able to shop online for just about anything, to play an online game or to watch a newly released movie. For others, it meant being able to stay on the island longer because they had a more reliable connection to do work.

Either way, the outside world was even more readily available, at least virtually.

Schoolchildren on the island were ahead of this curve: The main public school knew how valuable it would be for them to be technologically savvy, especially when students headed to college. In the last decade, those students have been encouraged to take language and advanced-placement classes online. Some in high school also take college courses. They learn how to download and evaluate statistics using palmtop computers.

Connie Boyle, a teacher at the school, helped implement the technology program. She had a vested interest in it, partly because she and her husband decided to raise their daughter on the island after moving here from Chicago 25 years ago.

"We were worried — 'How do you bring up a kid on very tiny Beaver Island?'" Boyle says. An answer came when their daughter, now a freshman at Michigan State University, called recently about her computer class.

"Mom, I don't get it," she said. "I'm helping everybody here. We did all this in high school."

___

Today's state-of-the-art Beaver Island school is quite different from the one Muggs Bass attended. For her, books were the only real window to the mainland, especially in elementary school.

Like many who settled on Beaver Island, her great-grandparents and a grandmother had come from Ireland, to farm, fish and find a better life. Her own father was a dairy farmer. Born Mary Margaret but called "Muggs" as long as she can remember, Bass went to a small school across the field from the family farmhouse.

Until her school combined with another in the island's main town, St. James, she didn't even know some of her own cousins on the island. Other than a trip to the doctor when she was a young child, she didn't go to the mainland of Michigan — "across," as the islanders like to say — until she visited an aunt in Detroit when she was 12 years old.

"It was big and noisy," she recalls. jaw crusher

She didn't mind that her family didn't have a television until she was a teenager. For a long time, the closest thing she had to a technological device was the family radio, which she sat beside with her father to listen to boxing matches.

Her world was small in those days. That's how she liked it.

But after she graduated from high school, she left the island to find work and she ended up living in other parts of Michigan and then Illinois, where she met her husband. They then moved to northern Indiana, where they raised their son and his children from a previous marriage. Always, she longed to return to the island one day.

___

It's not the kind of life that appeals to just anyone.

Donna Kubic, a registered nurse who heads the island's rural health center, gets that. She tells the story of a young woman who came to the island to apply for a job at the health center. The woman had planned to stay for a week, but left after staying just one night in a lakeside cottage.

It was too dark out there with no street lights, she told Kubic. Too solitary.

This is, indeed, a place where one doesn't take modern convenience for granted. There is one grocery store, a couple of gas stations, a handful of restaurants and bars but no movie theater. There is no full-time doctor on the island, though two visit from the mainland twice a month. Critical patients are airlifted off the island, by the Coast Guard if weather shuts down other options.

As recently as two years ago, if someone needed an X-ray, the films had to be flown to the Charlevoix hospital so a radiologist there could read them. Depending on weather, it could take days.

Kubic knew there was a better way. She persuaded the hospital to help her apply for a grant that recently helped her purchase digital X-ray equipment for the health center. Now images can be transmitted in a matter of minutes.

Next came video conferencing, connecting the island's nurse practitioner and physician's assistant to the mainland hospital's emergency room. It's the same technology that allows Bass and the other islanders to take part in the "Circle of Strength" cancer support group.

"Without it, we'd be out here, in the lake, without a lot of support," Kubic says. Eventually, she hopes that primary care doctors and specialists — even mental health care providers — will be more willing to offer their services to islanders (though so far, she says, they've been reluctant).

"I think it's just education, saying the technology is there, getting the docs used to it," she says.

___

When Muggs Bass moved back to the island 12 years ago, she had no idea that she'd soon be dealing with a serious health issue.

A year after she'd been there, she traveled to the mainland for her annual mammogram, which revealed cancerous tissue. She had surgery to remove a breast.

"Then I went along fine for 10 years," she says, until she got a cough she couldn't shake. One morning, she got up and said to her husband, "I need to go across, to the doctor."

Her lung was filling with fluid. The cancer had spread to her bones.

So for the past 18 months, she has traveled to the mainland every six weeks for an infusion of a drug that keeps her bones from fracturing, and also takes a daily pill to slow the cancer's growth. The goal is to extend her life as much as possible.

"I'm going to hold to this until I reach something else," Bass recently told her support group. "And then I'll have to make another decision."

The group in Charlevoix includes an 80-year-old woman with lung and colon cancer, as well as younger mothers who've survived breast cancer and those who are in the thick of the battle. They talk about infections and drainage tubes, mammograms and mastectomies. They somehow manage to find humor in topics such as constipation.

One of the moms, introduced to the Beaver Island group through video conference, thanked Bass for sending her a card and a prayer.

"I read it every day," the woman, who has 11- and 16-year-old children, told Bass. "I'm in it for the long term fight. I'm prayin' hard, too."

"That's what you do," Bass said, as she grabbed a tissue to dab her eyes.

Diane Gorkiewicz, who began the Charlevoix "Circle of Strength" six years ago, marvels at the intimacy that has developed so quickly between her group and the islanders.

"The only thing you're missing are all the hugs and stuff," Gorkiewicz told the islanders during a recent video conference.

"And the food," Bass said, teasing the Charlevoix group that they need to share the treats they bring to their meetings.

___

Joe and Phyllis Moore understand the dynamic.

Earlier this year, the longtime islanders were able to "attend" their youngest granddaughter's first birthday party via Skype. Guests at the party in Washington state sat at a computer to introduce themselves. The Moores saw the cake. They gave real-time wishes to the birthday girl.

"Just thinking about it, it almost brings tears to my eyes," Joe Moore says.

It's not ideal, but the best they can do — better than they could've hoped for, really. The hard reality is that the cost of getting off the island can be prohibitive.

Most islanders have to "wear many hats" just to get by, Moore says. In addition to his computer work, he's one of the island medics and also runs a local website that provides video footage of township meetings, as well as the school's soccer and volleyball games.

Phyllis Moore is now the assistant librarian, but when she moved back to the island after college, she and Joe ran a vacation lodge while he did his student teaching.

"Like most graduates, I was going to get off this rock and never look back," says Phyllis Moore, now 62. "And look where I am now."

Many young people who live here say technology — social networking and their cell phones included — make life on the island better for them, too. But in the end, they face the same dilemma as everyone else: How do you make a living here? And what if there's really no place for the kind of work you want to do?

Brontae Cole, a 17-year-old high school senior, will be heading to college next year and wants to become a homicide detective.

"There's one cop here, two in the summer if we get lucky," Cole says. She grins. "And not a lot of dead people."

Jewell Gillespie-Cushman, a 14-year-old freshman, also wonders where he'll land. His late grandfather, an island icon for whom he was named, was born on Beaver Island and lived here his entire life. Gillespie-Cushman isn't sure he could do the same, even with more contact with the outside world than his grandpa had.

"I'm still debating whether to stay here, or move over there," he says.

___

Like Muggs Bass, though, a growing number of people want to find a way ONTO Beaver Island — many of them among the thousands who visit each summer and would like to make it home. For many of them, technology is the key.

Jeff Stone and his wife, Sarah Rohner, were able to start spending more time on the island in 2006, when a satellite-based service began offering an Internet connection that was about two-thirds as fast as the newest service, and much faster than the sluggish dial-up service that had been the only option.

The satellite option enabled Stone to quit his real estate job in the Chicago area to start a website design business that he and his wife run from the island much of the year, though not without some initial glitches.

He recalls how snow from a huge storm covered their satellite dish, cutting off their Internet service just as they were about to launch their site.

"We ended up going out in the back yard and throwing snow balls at the dish," he says. That knocked off enough snow to get the Internet working, and they were back in business. But it's not always that easy, or quick.

Laurel Vietzen, a college professor, also from the Chicago area, who now spends several months a year on the island, remembers a violent summer thunderstorm two years ago that left much of the island without Internet and phones. "We had a daughter at the University of Iowa and we were hearing about terrible flooding in Iowa City," she says. "It was three days before we could reach her!"

Now that Internet service on the island is more reliable, many islanders say cell phone service is the big hurdle. One mobile provider's service works well here, though only on the upper third of the island — and outages happen more frequently than most would like.

Even those who reap the benefits of technology feel torn, though. They worry that it infringes on one of the very things they love about the island — its inherent, blissful peacefulness.

Technology is, at once, their blessing and their curse.

On a summer night, it's not unusual to see more than a dozen people sitting outside the library's memorial garden, on picnic tables and in their cars, tapping into the free wireless that's left on 24 hours a day.

At the same time, islanders and summer residents alike regularly complain about all the people who now walk around the main streets of St. James, staring at a smart phone screen or iPad instead of their beautiful surroundings.

"The technology is wonderful, but ... ," Phyllis Moore says. She raises her eyebrows, noting how, on a nice day, she isn't opposed to kicking kids out of the library after they reach their 30-minute time limit on the computers there.

Meanwhile, it used to be the joke that, by St. Patrick's Day, anyone who lived here year round couldn't stand the sight of anyone else. In many ways, communicating with the outside world helps with that, but not always.

"I don't think it's eliminated cabin fever or getting at each other's throats," Joe Moore says, chuckling. "Sometimes, I think it makes it worse because they can communicate more and get on each others' nerves even more."

___

Muggs Bass knows about the squabbles and the way a rumor can take on a life of its own, computer or no computer. She wasn't too happy, for instance, when she heard that some islanders were calling her cancer "inoperable." She didn't like the sound of it — wished they'd just ask her directly.

But that was nothing, she says, compared with the support she's gotten from her tiny island community.

"We joke. We kid. We take care of each other," she says. "I can't imagine living anyplace else."

When she got her latest diagnosis, islanders organized a "50/50 raffle" for her, where the winner is supposed to take half the donations. Instead, the winner gave his portion to Bass, a common outcome on Beaver Island. All up, she received nearly $9,000 to help with flights to the mainland and other expenses related to her illness.

"You talk about emotional," Bass says, tearing up again.

She recalls sitting down after that to pray and, as she might say, have a chat with God.

"I thanked Him, and thanked Him, and thanked Him. I was so grateful that I was able to come back and live here, and for holding me up at this time in my life," she says.

The support group and her new friends on the mainland are part of that.

For her, technology — at least her little slice of it — has allowed the best of both worlds.

George W. Bush calls Katrina photo a ‘huge mistake’

Bush regrets Katrina photo

Former President George W. Bush says it was a "huge mistake" to let himself be photographed looking from Air Force One down at the aftermath of Hurricane Katrina.

Bush reflected on the iconic photograph during an interview with NBC's Matt Lauer to promote his forthcoming memoir, "Decision Points." The photo was published widely and only reinforced the view that the Bush administration didn't act quickly enough or fully grasp the severity of the problems on the ground in New Orleans after the levees broke.

[Photos: Iconic images of Katrina's aftermath]

"Let's get to the picture that we may have seen more of you in the last couple years of your presidency than any other picture," Lauer said. "You're sitting in Air Force One, flying back toward Washington. You fly right over New Orleans and you look out the window."

"Yes," Bush responded. "Huge mistake."

The full Lauer interview airs 8 p.m. Monday night, with Bush's book hitting shelves the following day. But NBC released the following excerpt Friday:

LAUER: Yeah. And in comes the press and they take that picture. And it made you look so out of touch.

BUSH: Detached and uncaring. No question about it.

LAUER: Whose fault was it?

BUSH: It's always my fault. I mean I was the one who should have said, A, don't take my picture, B, let's land in Baton Rouge, Louisiana, C, let's don't even come close to the area. Let's -- the next place to be seen is in Washington at a command center. I mean, it was my fault.

LAUER: When the picture's released you write, "I immediately knew it was a problem."

BUSH: Of course. I'd been around long enough to know that when it was released. And the reason why we didn't land in Louisiana is because I was concerned that first responders would be pulled off their task and I'd be criticized. In retrospect,  however, I should have touched down in Baton Rouge, met with the governor and walked out and said, "I hear you. We understand. And we're going to help the state and help the local governments with as much resources as needed." And then got back on a flight up to Washington. I did not do that. And paid a price for it. cement crusher

[Then and now photos: New Orleans, five years later]

It's likely that most of the revelations in Bush's book will be covered before the title becomes available in stores.

The New York Times already snagged a copy of the book and revealed Tuesday that Bush once considered replacing Vice President Dick Cheney before running for re-election in 2004. Also, NBC released a previous excerpt in which Bush said that rapper Kanye West's criticism of him after Katrina—that he "doesn't care about black people"—was "one of the most disgusting moments of my presidency."

Iron Ore Crusher

Iron Ore: About 98% of iron ore is used to make steel - one of the greatest inventions and most useful materials ever created. While the other uses for iron ore and iron are only a very small amount of the consumption, they provide excellent examples of the ingenuity and the multitude of uses that man can create from our natural resources. Powdered iron: used in metallurgy products, magnets, high-frequency cores, auto parts, catalyst. Radioactive iron (iron 59): in medicine, tracer element in biochemical and metallurgical research. Iron blue: in paints, printing inks, plastics, cosmetics (eye shadow), artist colors, laundry blue, paper dyeing, fertilizer ingredient, baked enamel finishes for autos and appliances, industrial finishes. Black iron oxide: as pigment, in polishing compounds, metallurgy, medicine, magnetic inks, in ferrites for electronics industry. Major producers of iron ore include Australia, Brazil, China, Russia, and India.

Background   Iron ore crusher

Iron (Fe) is a metallic element and composes about 5% of the Earth痴 crust. When pure it is a dark, silvery-gray metal. It is a very reactive element and oxidizes (rusts) very easily. The reds, oranges and yellows seen in some soils and on rocks are probably iron oxides. The inner core of the Earth is believed to be a solid iron-nickel alloy. Iron-nickel meteorites are believed to represent the earliest material formed at the beginning of the universe. Studies show that there is considerable iron in the stars and terrestrial planets: Mars, the "Red Planet," is red due to the iron oxides in its crust.

Iron is one of the three naturally magnetic elements; the others are cobalt and nickel. Iron is the most magnetic of the three. The mineral magnetite (Fe3O4) is a naturally occurring metallic mineral that is occasionally found in sufficient quantities to be an ore of iron.

The principle ores of iron are Hematite, (70% iron) and Magnetite, (72 % iron). Taconite is a low-grade iron ore, containing up to 30% Magnetite and Hematite.

Hematite is iron oxide (Fe2O3). The amount of hematite needed in any deposit to make it profitable to mine must be in the tens of millions of tons. Hematite deposits are mostly sedimentary in origin, such as the banded iron formations (BIFs). BIFs consist of alternating layers of chert (a variety of the mineral quartz), hematite and magnetite. They are found throughout the world and are the most important iron ore in the world today. Their formation is not fully understood, though it is known that they formed by the chemical precipitation of iron from shallow seas about 1.8-1.6 billion years ago, during the Proterozoic Eon.

Taconite is a silica-rich iron ore that is considered to be a low-grade deposit. However, the iron-rich components of such deposits can be processed to produce a concentrate that is about 65% iron, which means that some of the most important iron ore deposits around the world were derived from taconite. Taconite is mined in the United States, Canada, and China.

Iron is essential to animal life and necessary for the health of plants. The human body is 0.006% iron, the majority of which is in the blood. Blood cells rich in iron carry oxygen from the lungs to all parts of the body. Lack of iron also lowers a person痴 resistance to infection.

Name  mobile crusher

The name iron is from an Old English word isaern which itself can be traced back to a Celtic word, isarnon. In time, the "s" was dropped from usage.

Sources  jaw crusher

It is estimated that worldwide there are 800 billion tons of iron ore resources, containing more than 230 billion tons of iron. It is estimated that the United States has 110 billion tons of iron ore representing 27 billion tons of iron. Among the largest iron ore producing nations are Russia, Brazil, China, Australia, India and the USA. In the United States, great deposits are found in the Lake Superior region. Worldwide, 50 countries produce iron ore, but 96% of this ore is produced by only 15 of those countries.

Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel. Due to the lower cost of foreign-made steel and steel products, the steel industry in the United States has had difficult economic times in recent years as more and more steel is imported. Canada provides about half of the U.S. imports, Brazil about 30%, and lesser amounts from Venezuela and Australia. 99% of steel exported from the USA was sent to Canada.

Uses impact crusher

In the United States, almost all of the iron ore that is mined is used for making steel. The same is true throughout the world. Raw iron by itself is not as strong and hard as needed for construction and other purposes. So, the raw iron is alloyed with a variety of elements (such as tungsten, manganese, nickel, vanadium, chromium) to strengthen and harden it, making useful steel for construction, automobiles, and other forms of transportation such as trucks, trains and train tracks.

While the other uses for iron ore and iron are only a very small amount of the consumption, they provide excellent examples of the ingenuity and the multitude of uses that man can create from our natural resources.

Powdered iron: used in metallurgy products, magnets, high-frequency cores, auto parts, catalyst. Radioactive iron (iron 59): in medicine, tracer element in biochemical and metallurgical research. Iron blue: in paints, printing inks, plastics, cosmetics (eye shadow), artist colors, laundry blue, paper dyeing, fertilizer ingredient, baked enamel finishes for autos and appliances, industrial finishes. Black iron oxide: as pigment, in polishing compounds, metallurgy, medicine, magnetic inks, in ferrites for electronics industry.

Substitutes and Alternative Sources  jaw crusher

Though there is no substitute for iron, iron ores are not the only materials from which iron and steel products are made. Very little scrap iron is recycled, but large quantities of scrap steel are recycled. Steel's overall recycling rate of more than 67% is far higher than that of any other recycled material, capturing more than 1-1/4 times as much tonnage as all other materials combined.

Some steel is produced from the recycling of scrap iron, though the total amount is considered to be insignificant now. If the economy of steel production and consumption changes, it may become more cost-effective to recycle iron than to produce new from raw ore.

Iron and steel face continual competition with lighter materials in the motor vehicle industry; from aluminum, concrete, and wood in construction uses; and from aluminum, glass, paper, and plastics for containers.
