EDGE SMEDGE

According to T-Mobile's web site they have EDGE support, but they don't say where. I never saw faster data rates driving to Disney World, including driving through Atlanta. Either it is something just not noticeable when downloading emails and basic web browsing, mostly on Pocket PC Thought's mobile forum site, or I never hit an EDGE network the whole trip. It felt like GPRS the entire time. I don't even know if the K-Jam gives a different indicator when it is on an EDGE network versus the "G" when it is on GPRS.

Have any of you T-Mobile USA users experienced EDGE with the K-Jam?
