Hey guys, as promised, I wanted to update you all as to the status of my loose iphone power button. I just returned from the Apple Genius Bar, where the Genius saw my issue, confirmed that it is indeed wobbly, and swapped out my phone for me. Before talking with him, I did check the demo phones just to cover my bases and to have grounds to challenge him if he were to try to tell me that the loose button was within the "normal range," but that never became an issue as the phone was swapped out without any hassle. Just wanted to share this experience with everyone out there since these forums have helped me so much, and I wanted to contribute. Thanks for reading.
