a.k.a. EDGE vs. EVDO Rev 0 vs EDVO Rev A
To think, the T-Mobile looked straight into my eyes and said that there wasn't much different in speeds between T-Mobile and other carriers. I found some real numbers on Richard's spreasheets on Swivel. His answer is resounding Sprint. The test is not quite what I wanted, since it is access from his location to various Speakeasy speed test servers. What I really want is a true test, using the speed test servers, from the various locations. In any case, the SF download speeds for T-Mobile vs. Verizon vs. Sprint is 144:930:1,081, uploads are 9:114:512 kbps. 9?!?!
Update: What we really want is a GPS-enabled phone (same phone) on all three carriers (four including Cingular), giving us location-based results for the different carriers. THAT would be a very nice article and mashup project.
