Sony Ericsson has finally released the W300i, its entry-level Walkman clamshell, to Cingular customers. As expected, it comes with a music player, external music controls, and an FM radio with RDS support, and it supports MP3, WAV, and AAC formats. Unlike its higher-end cousins, the W300i has only a VGA camera with 4X digital zoom, though it can still record and play back video. It retails for $179.99, but you can get it for $19.99 with a new two-year service agreement with Cingular. For more information on what we thought of the phone, please.
