Two questions actually: 1) I would simply like to remove all the AT&T crapware from the phone, not just visually, but I simply don't want them to be running in the background. What is the absolute minimum required amount of work to achieve that? Rooting, flashing, etc? I don't want to do anything that is not absolutely needed to achieve that objective. 2) Rooting and flashing.. are they reversible? If I need to exchange the phone for whatever reason in the future (for a refurbished one, etc), is AT&T going to refuse to deal with me because it's rooted or whatever, and is it possible to return it to its original factory settings?
