There have been lots of images floating around over the last month. This is the first one to show the smaller pin connector and the headphone jack on the bottom. The screen actually looks funny elongated. Seems like it should be wider and taller for the 4 inch screen.
No matter what the phone actually looks like, the features are going to be more important. What will Apple really wow everyone with?
One of the concepts for the iPhone 5 is a translucent phone. Apple has filed a patent for a glass phone but having the screen be translucent is even more awesome.
