Both me and a friend are on a solid WiFi network. We tried to Facetime and it loaded properly for a few seconds, then froze completely on my end, showing that my camera was working and his was not. His showed the reverse on his iPhone 4, showing it was frozen for me but his picture was displaying perfectly fine. Both did a full restore and not a back up, still same issue. I also noticed that my volume buttons are wiggly, is this enough to warrant a replacement? I'd prefer to exchange the entire box/headphones/usb cable and get a brand new device (instead of a replacement via brown box, regardless of refurb) since I'm still within 30 days of purchase (6 days as of today). Also is anyone else having the same facetime issue?
