Sony Ericsson unveils new phones

Sony Ericsson launched four new mobile phone models, including two in its Walkman-branded line, an Associated Press report said.

The report said the W850 was Sony Ericsson's first phone in the "slider" category and featured a 2-megapixel camera, as well as an upgraded version of the Walkman music player for tunes downloaded over 3G mobile phone networks.

The company, a joint venture of Sweden's Telefon AB LM Ericsson and Japan's Sony, said the phone allowed users to download music from the Internet and accepted several formats, including MP3, AAC and m4a, the report said.

The W850 also introduced a new service that allowed users to record a few seconds of a song, either via the microphone or the built-in FM radio, and then with one click send that clip to a database that would identify the track and relay information about the song back to the phone, the report said.
