man, if at&t is not going to let the 8820 do wifi for email and phone, in addition to browser, hard to justify my moving "up" from 8800. i have an unlimited blackberry data service (not sure i could find on new att site) and i can't find anything about uma or wifi. maybe it's too early but how much want to bet even after att starts selling 8820 to consumers there is no easy way to get a straight official answer on these issues
