I have a 32GB iPhone 3GS. It is locked to AT&T and has never been jailbroken. I am one of those boring people who just uses the my iPhone exactly as Apple and AT&T expect me to like a good little boy. My question is this: How did the tethering option end up in my Settings->General->Network settings? I thought that wasn't supposed to be there unless your service provider provided the option or you hacked your firmware. P.S. I don't know if it actually works or not since I just noticed it.
