On Sunday, the world’s fourth mobile phone maker, Sony Ericsson, revealed a new smart cell phone, which uses motion control technology. Z555 can be silenced by a single wave of hand. And this is only one of the new mobile phone’s cool capabilities! For example, the motion control technology also allows users to activate the snooze function of their phone by waving across the device.

Sony Ericsson launched Z555 and two other impressive cell phones with the occasion of this year’s Consumer Electronics Show’s news conference from Las Vegas. Excepting the tri-band Z555 model, which features also a music player, FM radio and a 1.3-megapixel camera, Sony Ericsson unveiled two new models for its Walkman music phone handset line-up, including the Walkman W760 model.

The W760 mobile phone features satellite positioning technology, as well as mapping software from Google, which allows people to follow step by step directions to their different destinations.

Sony Ericsson announced that the Z555 flip cover mobile phone will be available in the first quarter of 2008; for the Walkman W760 model people will have to wait a little longer, until the second quarter of the year.

Sony Ericsson’s Walkman branded music phones have been quite successful in the recent period. However, despite this fact, Sony Ericsson still trails Nokia, Samsung Electronics and Motorola in the global market for cell phones.
