First off let me say Iphone 3G WILL NOT work on T-Mobile, DIFFERENT HARDWARE freq.

Now my question is on the 3g speed, att decided not to wait until the gov clears up higher end freq for mobile carriers to use and uses lower end freq for the 3g Iphone. While T-Mobile is waiting to for the clearance to lunch there full 3g network at higher. I’m just wondering what does this mean? Is tmobiles 3g faster then att’s 3g network?
And for those of you on the new att 3g phone is the speed that much faster? I heard the battery dies a lot on the phone, what’s your take on it?
