Apple has filed for a new trademark, 'Mobile Me', once again raising speculation it plans to launch a mobile phone.

The trademark covers numerous areas - including computing devices, mobile devices, mobile services including digital music, video, games, email, and messaging across Internet, intranets, extranets, television, cellular, and satellite networks - the four separate filings reveal.

The trademark applications (filed January 5) also cover telecommunications services.

"We believe this is further indication of (Apple's) strategic direction to extend its iPod, iTunes and Mac franchises into new business areas, including smart phones, value-added mobile content services, and the broader consumer electronics space," American Technology Research analyst Shaw Wu told Reuters.

Apple's chief designer, Jonathan Ive, has been a long-term critic of mobile phone design, expressing puzzlement that phone designers don't put more focus on the end user experience in their designs and user interfaces.
