Can anyone confirm if tethering works on the iphone 3gs yet for 3.1.3 via benm carrier thing? I HAVE NOT jailbroken my phone, and dont wish to. I have ATT. I have the phone currently on 3.0.1 with the benm tethering working, but I wish to update so I can get mms, so can anyone confirm if this is legit working again? Thanks for the help!!
