Filed under unlikely, we hear rumors today that Apple is looking at three prototype versions of the iPhone 5. We have already heard about two of them which include the iPhone mini that has a 2.5 inch screen. The next model I believe is the regular iPhone 5 with a 3.5 inch screen, although other rumors hint at this model having a slightly larger 4 inch screen.
Finally, Apple are rumored to be testing an iPhone with a slide out QWERTY keyboard. This is the part of the rumor that I find most unlikely as it would be a major departure from the regular virtual keyboard that has been on every single iPhone since launch.
The rumors come from a Taiwanese website (translation). The translation is quite rough, but the message they share does come across.
In regards to the Apple.pro website its self, it has in the past managed to get hold of information about Apple that has been correct, so at this point we can't write this one off. However, I'm not a fan of the slide out QWERTY myself, so for me the regular iPhone form factor suits me.
Just a few more months wait now and we'll find out for sure which direction Apple is headed.
