The Sony Ericsson W595 is one of Sony's higher-end Walkman phones. It comes with Sony's Walkman music player interface and stereo speakers, track identification, Sony's SensMe custom mood playlists, shake audio controls, and a 2GB M2 card which can be expanded up to 8GB. The W595 is also 3G-enabled, and uses the high speed network for videocalling with the built-in 3.15-megapixel digital camera or data transfer at 3.6Mbps. It also includes NetFront Internet browsing, a picture editor, Bluetooth connectivity, and an accelerometer sensor to autorotate the screen. Its display is large, at 2.2"-diagonal, and features 256k colors. Note that there are three versions of this phone, the W595, the W595c and the W595a, the latter two released for China and North America, respectively. Neither the W595a nor the W595c have 3G-connectivity, only the original W595, even though they are all quad-band receptive on the 2G network.
