This purported photo of the next-generation iPhone (iPhone 6) has surfaced on Social network Weibo. The front display glass looks significantly larger that the 4-inch display on the iPhone 5s, which indicates that it could either be the rumored 4.7-inch display iPhone or the 5.5-inch display model. The report did not say.
As is the case with all rumors and leaks, there is no guarantee that Apple will be releasing the products mentioned above.
Update:
Another French website suggests it might be the 4.7-inch iPhone 6.
In other news, Macrumors (via Nowhereelse.fr) has published an image the purported batteries for the iPhone 6 in a production tray.
