hey everyone! i have a question... i've got a friend who refuses to jailbreak his iPhone (for a couple of reasonable reasons) but wants to tether his internet connection. he's done that in 3.0, but once he upgraded to 3.1.2 (or 3.1 in particular) he wasnt able to do so anymore. any ways to do some tethering without jailbreaking the phone? thx in advance!
