| I've got a bluetooth phone and I have used the GPRS with T-Mobile. The speed varied based on how good my signal strength was. You will have to upgrade your plan to unlimited data, $20/mo. Another option would be to signup for T-Mobile hotspots if you're travels will keep you close to Starbucks and Kinkos. After having both and testing them both, my father quit the GPRS plan in favor of using the Hotspots.
