Edge almost is equal to 3g, depending on its implementation. 3G solved alot of use issues, such as talking, and data simultaneously , and 'new' specs to forward data speeds.
Just from the top of my head, AT&T's deployment of EDGE typically peaks between 150-250Kbps - other 3G technologies such as EVDO REV.A and whatever AT&T uses easily achieve 1.5Mbps and greater. -- www.aimless.us - irc.aimless.us channel #fix
