Anyone got any answers as to why tethering does not work with our Iphones? I have an S with 3.1.3 so does that mean that tethering does not work for sure? I'd like to try it anyway to see if it will work, so how do you do it? How hard is it to downgrade to a version that does have tethering? At$T should is impressing me less AND LESS all the time. No 3g in about half my state and no tethering, why are we paying so much?
