Sony Ericsson have trademarked the name Xperia for what the trademark application shows is a range of seriously well equipped mobile phones. Specifically, the trademark lists functions such as:

• camera
• instant messaging
• e-mail
• Internet connectivity
• radio
• record, play, transmit, receive, and/or manage music and video
• play electronic games
• upload photographs and text onto online journals or web logs
• function as a personal digital assistant (PDA)
• function as walkie-talkies
• satellite navigation
• remote control for computers and run multimedia presentations

Now, a lot of these functions have already been squeezed into many of Sony Ericsson's existing phones. However, by trademarking a new brand name, it does seem as though a new range of high end Sony Ericssons are just around the corner.[Source: Trademork, via EngadgetMobile]
