Apple iPhone 2G (1st Generation) and 3G (2nd Generation) Compared (Repair, Unlock, Jailbreak, Auckland)
Whether you love or hate Apple, you must admit that the iPhone revolutionized cell phones as we know them today. Before the 1st generation iPhone hit the market, the top selling phone for the past three years was the Motorola RAZR. However, not too long ago, the iPhone and Apple enjoyed monumental achievement by becoming the best selling phone in the third-quarter of 2008. It’s been almost two years since the release of the original iPhone, and only a few months
ago Apple released the iPhone 3G. Both phones are still missing some basic features, but there has been an improvement in the latter version. In this article, we will cover the differences between the iPhone 2G (or first generation) iPhone and it’s newer counterpart, the iPhone 3G.

Design and Dimensions
Even though there aren’t too many differences in the exterior of the models, we are going to point them out before we get to the hardware. The screen size is exactly the same at 3.5" on both models, which provides for an ultra-clear 480×320 screen resolution. The rear of the original iPhone has a smooth metal finish with a black strip at the bottom. The front of it has a shiny metal piece that surrounds the side of the phone and ends behind the screen. The iPhone 3G has a smooth piano black or white finish. It also has the shiny metal piece around the outside of the screen. The iPhone 3G features buttons that are made from a shiny metal, excluding the home button. This gives them a sturdier feel compared to its predecessor. The shape of the 3G phone is a major difference as the original iPhone is a little thicker and completely flat when set down. The 3G has more of a round feel to it that flattens out slightly around the edges. It has been said that the screen of the 3G heats to a warmer temperature than that of the original iPhone.
Features & Technical Specifications
Once we get under the hood, we begin to see where the 3G separates itself from it’s older brother. The iPhone 2G only supported WiFi, GSM, and Bluetooth. This means its speed surfing the Internet were quite limited. The iPhone 3G introduced 3G speeds to Apple’s flagship model, and it also supports WiFi, GSM, and Bluetooth. This makes for a better experience surfing, watching Youtube videos, and downloading data onto the phone from the Internet. The first generation iPhone supported the following frequencies: GSM and Quad-Band (850, 900, 1800, 1900 MHz). The iPhone 3G supports all of those frequencies, but added to the list quite a few more to enable running at 3G speeds, including UMTS/HSDPA (850, 1900, 2100 MHz). The iPhone 3G also supports GPS, which was not included in the original iPhone.
Both phones have a 2MP camera, but do not feature a video recorder. The iPhone 3G weighs 4.7 ounces compared to the 2G’s weight of 4.8 ounces (not a notable difference). The only downside to 3G capabilities is that it eats into battery life. The iPhone 2G beats out the newer version in that regard by providing up to 8 hours of talk-time compared to 5 hours with the 3G.
Bottom Line
Comparing two great phones is always hard, but Apple made a great move by creating the 3G iPhone. The iPhone 2G is impressive, but with the features the 3G provides and the transition with new phones all moving to 3G, it’s a definite requirement if Apple wants to maintain its new status as the #1 selling phone in the US.

Your Apple iPhone 3GS may May Fight Alzheimer's, Mouse Study Says. (Tech, news, report, jailbreak, unlock, repair, Auckland)

After years of speculation that cell phones may harm your brain, new research suggests they may actually fight Alzheimer's disease.
Yes, you heard right.
Microwave radiation from cell phones may protect against and even reverse Alzheimer's-like symptoms, according to a new study involving genetically tweaked mice.
(Related: "Rat Made Supersmart — Similar Boost Unsafe in Humans?")
The results were so surprising that study co-author Juan Sanchez-Ramos didn't believe them at first.
"It's such a dramatic and counterintuitive effect," said Sanchez-Ramos, a University of South Florida neuroscientist.
"I joked that the animals must have been mislabeled or that the power wasn't switched on."
Mobile Phones Provide Protective Radiation?
The primary culprits in Alzheimer's disease—which is marked by dementia and cognitive decline—appear to be sticky brain deposits known as beta amyloid plaques, which can build up between nerve cells.
In the experiment, scientists examined the effects of cell phone radiation on 96 mice that were genetically engineered to develop beta amyloid plaques and thus Alzheimer's-like symptoms. The mice normally developed the first signs of the disease around 6 months. By 8 months they were already experiencing cognitive declines.
Both the Alzheimer's-prone mice and normal mice were then exposed to cell phone-level microwave radiation for two one-hour periods daily for seven to nine months.
The study found that if cell phone exposure began before the genetically engineered mice started showing signs of Alzheimer's, they were less likely to develop symptoms later on in life.
These mice performed as well on memory and thinking-skills tests as normal mice without Alzheimer's. For instance, the mice were given a cognitive interference task that tested their ability to remember something after an interruption. The team also put the mice through a three-armed Y maze, which measures basic memory function.
(Take a brain quiz.)
Furthermore, the genetically engineered mice that were were exposed to the cell phone radiation after they had already begun to show cognitive deficits generally saw their memory impairment disappear after several months of the radiation exposure.
Of Mice and Men and Alzheimer's
No one knows how the radiation protects against Alzheimer's, but the team has some ideas.
One is that the microwaves create cellular stress in the brain, and that the stress jump-starts DNA repair mechanisms in the brain.
For instance, scientists already know that "minor insults" such as toxic substances or low oxygen will improve the brain's ability to repair damage to proteins and DNA, Sanchez-Ramos said.
However he cautioned that the experiment was not "a perfect replication of cell phone use in humans."
For instance, the lab mice were exposed to cell phone radiation over their entire bodies—not just to their heads.
"It's an interesting finding and perhaps it could be translated somehow to a human test," said David Knopman, an Alzheimer's expert at the Mayo Clinic in Rochester, Minnesota.
But he also urged caution against assuming the findings would apply to humans.
"What goes on in mice may not have anything to do with people," said Knopman, who did not participate in the study.
"This animal model of Alzheimer's is useful, but there's still many questions about whether it's ultimately valid [to humans] or not."
That's because Alzheimer's disease does not manifest itself in the same way in humans, said George Perry, an Alzheimer's expert at the University of Texas, San Antonio, who was not involved directly with the research.
"In most people, the development of amyloid plaques is related to the aging process—not because they're genetically modified," Perry said.
Not All Bad?
Nevertheless, the "pretty dramatic" research raises the possibility that health effects of cell phone radiation are not all harmful, added Perry, who is also editor in chief of the Journal of Alzheimer's Disease, in which the January 6 study was published.
How, cell phone radiation affects humans—if it all—is currently a topic of intense debate.
Some scientists, for instance, claim that cell phones can lead to increased risks of brain cancer. Such concerns have led the U.S. state of Maine to consider requiring that cell phones carry warning labels.
The new study, though, "puts the debate in a perspective where we need to consider a broad range of effects of cell phone radiation," Perry said.
