A belated US Patent via an Australian filing mysteriously surfaced this month revealing a stunning nano-phone concept in development at Apple.

The design involves a very sophisticated yet complicated dual-surface user interface. The full face-side of this device will be nothing more than a display, much like the iPhone is today, while the back-side will be primarily dominated by a force-sensitive touch based surface. Your fingers, which act as a cursor, control the face-side UI by the back-side etched controls. The dramatic design will offer users a variety of interfaces or modes to work with including one for a phone, text messaging, a traditional iPod, a camera mode and more. The design may also, according to Apple, simply offer consumers with a dual-sided display option in lieu of a force sensitive controller surface. On one hand, the design appears to be nothing shy of being revolutionary once again. On the other, the concept seems to be overly complicated. I’m sure that once we see it, it’ll all make sense. Yet until that time it arrives, I think that Apple’s design could be hotly debated.
