The U.S. Patent and Trademark Office published an interesting continuation patent application from Apple yesterday. Apple's patent says, "the connector 62 may be a power connector such as the MagSafe power connector manufactured by Apple Inc. of Cupertino, Calif. The MagSafe power connector utilizes a magnetic attraction to help retain a corresponding connector thereto."
Plenty of speculation could be made about what MagSafe charging means for iOS devices...
