For those of you in metro NYC using AT&T 3G, what kind of network speeds have you been experiencing lately? I've read reports that AT&T's 3G network quality has degraded with all of the new iPhone 3G users in the region.

I'm considering moving to AT&T due in part to greater unlocked 3G phone choice (i.e. more than T-mobile's zero), and better rural service when on vacations and the like. But when I'm back in metro NYC, I tether only occasionally and the EDGE speeds I'm getting on T-mobile where I am seem reasonable for that light use. If AT&T 3G speeds are only marginally better, then it might not be worth it for me.
