I went to collect my iPhone 4 for RMA after a week. But unfortunately the replacement iphone4 had the same loose button issue and worst, loose volume buttons too. I didn't accept the replacement and asked for another one. Also, the replacement looks new, but they don't give you a replacement from a new batch. The replacement I got still had philiips screws and not torx screws. I complained on twitter @maxislistens right away, and not long I got a call from their CS. They'll try and get me a better replacement.
