New documents suggest motion tech could be at the heart of the upcoming new model.
Mac Rumours reports on two Apple patent applications that indicate the tech giant has been wrestling with the problem of gesture control in a portable device, and specifically, the issues involved in gesturing to a handheld when the user itself is moving.

One patent outlines an idea where the iPhone can detect when a user is moving and automatically enlarge the UI accordingly, reducing the scope for error.

More interestingly, however, the patent diagrams seem to show a front camera on the iPhone/iPod Touch Ė something that isnít present on either of the existing models.

Such a development would, in telephony terms, pave the way for video calling. But from a games perspective it could add a whole new dynamic to the current touch screen and accelerometer functions.
