The Sony Ericsson W350 is a tri-band handset that duals as an mp3 player. It has a 256k-color screen and candybar-like design where only the bottom keypad cover flips open - when closed, the cover provides music player keys. The W350 uses Sony's Walkman music player interface to play mp3s, and this comes with track recognition and custom playlists. It has 14MB of internal memory, and includes a 512MB Memory Stick Micro (M2) and this can be expanded up to 4GB. Also included is a 1.3-megapixel digital camera with picture editor, though it is not capable of video capture. The W350 is Bluetooth connective, and has a stereo FM radio receiver as well. The phone has three different versions: the W350i, W350c and W350a. The only differences are their reception bands and that the W350c has Chinese character input.
