Holy crap! 4S on AT&T:
Ping: 322ms
Download: 3.52 Mbps
Upload: 1.08 Mbps
Now, this is in a tiny farming town with a population of 3000 (Sunderland MA). We are right next to a town (Amherst MA) with 30,000 and the flagship campus of the University of Massachusetts with 20,000 students, but still. With my old 3GS I was getting .75-1.25Mbps down and around .25 up, and my brother's 4 didn't get much better than that, so this is a three- or four-fold speed increase! Holy crap. I can't wait to see how it does in Amherst, where I was getting 4 Mbps down before.
