It’s widely believed that Apple will unveil two iPhone models at once at its next event. One model has been dubbed the ‘iPhone 4s’ while the other device is rumored to be the iPhone 5. The 4S will supposedly be a cheaper, re-tooled version of the iPhone 4, while the iPhone 5 will consist of noticeable upgrades, like a faster processor and better camera.
The iPhone 4S is supposedly codenamed the ‘N94’ prototype internally at Apple, and the newly-released iOS 5 beta 7 gives some more details about the mysterious device.
