Like jd said, you should be good. I do suggest you read ALL of the information available about it in these forums before you buy it, so you don't end up being one of the people that didn't read and now need run back here to have people fix it for you. You definitely don't want to be one of those people. There are already way too many of them. So read up, learn, plan, buy, modify, and enjoy.

Make sure you read and understand the "PINNED" threads in the "General" and "Q & A" sections of the AT&T S4 forum BEFORE you ask for help. Use the forum's "search" function to find posts with additional information. You should not expect others to help you if you haven't tried to help yourself first. Also, read, understand, and follow the "XDA" rules.
