The upcoming smartphone from the company could have 4 inches, as against 3.5 for existing models. The screen size would be similar to a Samsung S Galaxy Nexus or Google S.
In addition, other rumors circulating on specialized websites, indicate the existence of a prototype of the iPhone 5 which has a retractable sliding keyboard. The device would then look like an iPhone 4 but under which it would be possible to drag a physical keyboard.
The future iPhone 5 could also be compatible with the NFC, which would transform it into a means of contactless payment (such as the Nexus S by Google).
