Apple Trademarks 'Mobile Me'
MacOSXRumors notes that Apple has filed for a trademark for the term "Mobile Me":
The name appears to be under a number of descriptive categories including "telecommunication services", "portable digital electronic devices and software related thereto", "providing digital music from local or global communications networks" and "computer services".
The trademark was filed on January 5th 2006 at the U.S. Patent and Trademark Office.
The rumor site suggests that this may have to do with Apple's speculated entry into the mobile phone market, but appears it may have to do with providing iTunes wirelessly over cell phone networks.
