iPhone lovers may have a clam in their future. Patents have been filed for an iPhone design that opens like a clamshell to make a "dual sided trackpad."
That means you can access the interface from both front and back of the phone, and, when you want to dial number, all you have to do is draw the digits on the pad. It will be useable whether open or closed, plus double the screen space for widgets and information.
