A schematic claimed to be for a case for Apple's anticipated fifth-generation iPhone shows a larger area for the home button, a slightly larger screen, and the return of curved sides like on the iPhone 3GS.



From Apple Insider:

The documents allegedly come from a Chinese case manufacturer, and were obtained by MobileFun.co.uk (via Cult of Mac). They show a design with curved sides, similar to iPhone models released before the current iPhone 4.

On the front, the case appears to have a larger, oval-shaped opening for where the device's home button would go. That could lend support to rumors from earlier this year that Apple's next-iPhone would feature a multi-touch "gesture area" in place of the current home button.
