However, since there was no report from internal sources that reveals the presence of one of the bigger screen, probably to give the true picture, we face the future five or iPhone to a first prototype of this new terminal currently under testing.
For several months there are rumors that the next iPhone will mount a screen larger than the current (assumed to be 4 inches), but excluding various designs and mockups, this is the first image that appears to show the new device with a display actually larger, although 3.7 inch.
According to the drafting of 9to5Mac the image may actually be authentic as you can clearly distinguish the new proximity sensor, this white iPhone 4, the device has not yet officially available for purchase.
