Apple has backup iPhone 4G?

Rumor has it that Apple has a second iPhone 4G to reveal to the masses this June at WWDC, assuming they decide to ditch the one which has been leaked to the public. According to Digitimes (who don’t really have a good track record when it comes to rumors), Apple was actually working on a parallel project codenamed N91, where it will resemble the iPhone 3GS physically much more than the N90 which we’ve seen getting lost in a bar. What do you think of this – will the N91 be classier looking compared to the N90?
