Apple has filed to trademark the phrase “Mobile Me” … speculation is this is leading up to an Apple iPod phone. One designed by Apple, and not one that simply licenses the FairPlay DRM as the ROKR E1 did.
If you search the U.S. Patent Office site you can find the Mobile Me information. This sounds like a heck of a lot more than an iTunes Phone. I am not sure whether it would be a good call for Apple as the main basis for an iPod is music. Although they would sure as hell sell tonnes of these!!!
