Below is a picture of a white iPhone 4 and it is running on T-Mobile. Boy Genius got pictures of a prototype. We now know that a white iPhone is finally coming. Boy Genius says that this iPhone 4 is powered by a “test version of Apple’s iOS” with some special apps that are not on regular iPhones.
One is called Radar and the other is a directory of the Apple employee directory. This prototype is named model N94. Verizon’s was N92 and AT&T’s is N90.

Apple has unleashed a new iPhone to select developers in a sort-of preview of what’s to come in the company’s to-be-released iPhone 5. Unofficially dubbed the iPhone 4S, the smartphone look and feels just like a standard iPhone 4, but with one major difference: Instead of an A4 chip nestled within the device’s insides, Apple’s plopped in its dual-core A5.
According to a report from 9to5 Mac, this iPhone “4S,” as certain developers have nicknamed it, is completely indistinguishable from a standard iPhone 4. The only differences being that the iPhone 4S comes with the A5 chip, as mentioned, and that it must be locked in a developer’s safe each evening.
So what’s the big difference between Apple’s A4 and A5 anyhow? Well, the most obvious difference is that it’s a move from a single-core ARM A8 design to a dual-core ARM A9 processor. The 40-nanometer A9 processor runs a variable clock speed of around 900 MHz on average, and comes with double the L2 memory of its predecessor chip–an increase from 512 KB to one full megabyte.
