A 3G Americas press release from today states that there are over 100 carriers worldwide working on or already support EDGE. In the US, AT&T is the furthest along, followed by Cingular and T-Mobile.
EDGE customers can expect to receive average data speeds between 110-130 kbps, with bursts to 200 kbps, when using an EDGE modem card in a laptop, and several EDGE handsets are available that can also be used as modems for wireless connections.
