Well never thought of that, I haven't tried that cause i don't have evdo, or worldcall wireless.... it's a possibility but i doubt it, I've tested a USB flash drive and the mobile reads it as "hard disk". i tried a USB wifi card and a dialogue appeared saying " unknown device , drivers not found". evdo drivers are on the evo device so it is a possibility but not tested, and even then will those drivers work with windows mobile??? don't know.
