Grandfathered unlimited as well, I wasn't aware that facetime didn't work with unlimited but I guess I shouldn't be surprised since AT&T is trying to get folks off it. I don't use facetime so I really don't care but I'm glad I still have my unlimited as the LTE burns through data quick! I'm not a big data user, on my iPhone 4 it would show 450-650mb per month, I just checked my usage on the iPhone 5 which I got on 9-21 and it shows 2GB! Sure I may have done a little extra surfing the first week to play with the new toy but almost 1.5GB worth extra for 1 month... I don't think so.
