Hmm...it was working earlier and I just wanted to make sure so I thought I'd try again. When I turn the tether option on, it worked. Turned off 3G to test WiFi tether. Turn 3G back on...get some message from AT&T saying I should contact then if I want to set up internet tethering. ./ Option to turn tether on/off now gone. WTF? Anyone else have this?
