Is this really exclusive on the 3G S? I updated my primary 3G and I have this feature but the other phones that I've updated to 3.0 (friend's phones) don't, besides one. Does anyone have any idea how to get it to work without SSHing it onto the phone?
that is because you didnt change it from jailbreak before you updated. Some of these features stay. To get it you have to jailbreak (the new 3g jailbreak is out)
