Hey guys, just a quick question. I want to upgrade my iPhones plan to unlimited text messaging. Right now I have 1500 and I push the limit almost every month. Is there any way to do it without calling them. I hate having to give them my whole life over the phone before being able to talk to someone that will be able to help me. it always takes like 30 minutes. So is there any way I can do it through iTunes or on att's website?
