I currently have unlimited text messaging through AT&T, and since I have so many friends switching to iPhones I rarely use the "text message" aspect of the phone and have been using iMessage a lot more, so I'm thinking of downgrading my text messages. My question is if I want to go back to unlimited text messaging in a year from now, will I be able to do it? I could've sworn I read that AT&T was doing something stupid with their text messages a few months ago.
