I do not have an aircard, but do have an
EVDO enabled phone (and had another previously) My Moto Q9c had gotten speeds of up to 900kbps and my new Samsung Instinct gets around 500kbps (due to its browser being s***ty if you know what I mean). The demo units at Sprint and Best Buy for the Aircards however show speeds of up to 1.2Mbps which is pretty impressive, and the uploads are quite nice running approximately around 200-300kbps in the Columbia, MO area.
Hope that helps, Chris
