Wireless charging for iPhone 5.

An Apple patent indicates the company could be readying a wireless charging system that would be built into its iMac computers to charge nearby wireless devices, such as a keyboard, mouse, "and -- yes -- iPhones containing the appropriate receivers," according to FoneHome.com, which headlined its story "Wireless iPhone 5 charging patent revealed."

FoneHome had picked up on the patent information (WIPO), which of course doesn't mention iPhone 5.

Apple's approach sounds similar to that of MIT researchers (and many others) using electromagnetic resonance between coils to transfer energy without wires and then convert it into power. The MIT team just over a year ago. 

Forget the "iPhone 4S."
