AT&T Service
The W580i operates on GSM 850/900/1800/1900 networks and can handle high-speed data connectivity via AT&T's EDGE network (which stands for "Enhanced Data Rates for Global Evolution"), with availability in more than 13,000 US cities and along some 40,000 miles of major highways. This third-generation, high-speed, mobile data and Internet access technology is fast enough to support a wide range of advanced data services (with average data speeds between 75-135Kbps), including video and music clips, full picture and video messaging, high-speed color Internet access, and email on the go.

The phone has a built-in web browser for MEdia Net downloads and mobile web browsing. AT&T's MEdia Net service lets you do more than just stream videos--it enables you to receive and send emails, read news headlines, get weather updates, download games and ringtones, and more. It also features AT&T Mobile Music, which provides access to the Napster subscription music service in addition to Music ID song-recognition software, music videos and The Buzz music news portal. (A MEdia Max subscription bundle is recommended for accessing AT&T's Internet, video, and music services.)

Phone Features
The W580i Walkman phone offers a full-function digital audio player that's compatible with MP3 and AAC files. The front of this slider phone includes dedicated music control buttons, and it includes Sony Ericsson's innovative "shake to shuffle" feature. With Shake control activated, press and hold the Walkman key and flick your wrist. A vibration lets you know that the track has been changed--a new song from your current playlist is randomly selected and automatically played.

With the TrackID service, you can identify any song that you can hear by just recording a snippet of sound using the microphone. After sending the file for recognition, you'll have the name, artist and album sent to your phone. Other Walkman features include MegaBass enhancement for added depth of sound, a flight mode that lets you keep listening to tunes with the phone's network connectivity turned off, and Disc2Phone software for easy transfer of song files between phone and PC. It also includes a built-in FM radio with RDS, which displays the name of the currently playing song (when tuned to compatible radio stations).

This phone provides Bluetooth version 2.0 wireless connectivity with EDR (enhanced data rate), and includes profiles for communication headset, handsfree car kits, and audio/video remote control. With the A2DP Bluetooth profile, you can stream your music to a pair of compatible Bluetooth stereo headphones. You can connect your laptop (either via Bluetooth or wired USB) and enjoy dial-up networking--surf the Internet, send email, and access files from a server.
