answer:It is my understanding that unless you are willing to jailbreak your phone, neither AT&T nor Apple will allow you to tether the phone. See here for an article on the matter. As you’ll read, Apple is apparently in talks with AT&T to create a tethered option, but that does you little good now. All that said, it is conceivable that AT&T could get testy when they see your data transfer getting kinda high. If you find you can pwn it, here’s some info that will help with the tethering process.
