Sad to say goodbye as I really like the phone, but I have the opportunity for the Thrill (now) or the SGS2 (when released). No problems with the Infuse, but I just want to get a later phone since I have the chance. My question: has anyone returned a phone with a custom ROM before? Since technically I'm not trying to exercise the warranty, there shouldn't be a problem, right? I don't want AT&T to come after me for the full price of the phone after the fact, but I don't want to waste time reverting to stock if it's not necessary.
