100mbps for all of 25 minutes until you get throttled to 200kbps.
All carriers throttle, with AT&T being probably the worse. But if you download at 100mb for 25 minutes you deserve to get throttled lol. So far, I can tell you, that its been consistent 100MB down all around town, and at my work, lately I just whip the phone out to destroy my AT&T and Verizon friends. This is even during peek hours. The phone feels so fast now its crazy. I just go to whatever carrier is the fastest, and right now its T-Mobile by a longshot, all those people buying AT&T phones for band 30 and they will never see anything from it, just move to T-Mobile if you want blazing fast speeds, of course be sure to check your area first.
