I’ve got a laundry list of issues with my HTC HD2 (Twitter OAuth fix is a no-show so far, Windows Phone random reboots, no Windows Phone 7 planned, slowest music player ever — that’s just getting started) but the one bright spot is the ability to tether over a USB connection to T-Mobile’s 3G network. I just ran a speed test and here are the results: 3.82 MB/s download and 0.63 MB/s upstream. Sure beats 56K!
