For Apple, the iPhone 5 must be the best kept secret yet. Why? Because so many credible sources are pointing to a completely redesigned iPhone along with a 4S, and we've yet to see a leak of the device. The only visual hint we got, was the Photo Stream icon, the leaked design schematics and cases. So if the iPhone 5 isn't leaked until the announcement, and it debuts. Will this be Apple's best kept secret yet? Or are we all in for a very disappointing event, with only an iPhone 4S.
