I have seen speeds of 1.3 Kbps up, 500 down on AT&T with USB and Bluetooth. I currently have my Bold tethered but use it as a backup for now. Once my Sprint card contract expires, I plan to use this as my primary mobile data connection. The sprint EVDO-RevA gives me 2 Mbps and such sustained so I hope that in its prime locations, ATT gives me similar speeds
