At Anticipation, I had my iPhone tethered throughout the con, and it worked great. (See here for directions: http://tinyurl.com/n26g4k http://tinyurl.com/n26g4k) Furthermore, as far as AT&T was concerned, I hadn't been transmitting any data--I checked that very specifically with an AT&T rep on the second or third day of the day. Note that my phone is not jailbroken. Unfortunately, I allowed the phone to update itself and it wiped out the new network profile that enables this. I need to reinstall it.
