EDIT - Explanation from my later post: Original post: I can't be the only one, but a quick search shows otherwise. I'm on 3.1 jailbroken, and tethering is working perfectly fine. I turn it and, and sure enough, it works. I'm using the AT&T 5.0 carrier file, not the official one. Aside from that, I haven't the slightest clue what I did different than anyone else. Is this "just working" for anyone else?
