Sony Ericsson will unveil a mobile phone-cum-digital music player early next month. The phone/music player is expected to hold multiple CDS and work with the Sony Connect music service.

The phone will carry a name which has already appeared on some 350 million music players over the last 25 years: the Walkman brand of Sony Ericsson’s parent company, Sony. The Walkman phone will play music file formats such as MP3 and AAC (Advanced Audio Coding).

Sony Ericsson will unveil the phone next month, and will go on to exhibit it at the Cebit trade show in Hanover, Germany, which opens March 10.
