I have the same issue. The black part on the bottome is a little lose on the back right side. Obvioulsy you can not just buy a new apple case for the iPhone and put it on. Is anyoen else having this issue?
I have a similar issue. I dropped the phone from about 2 feet, and after that, the black part seems to be loosen a bit. What's more, the home button seems to be moved slightly inside, I guess something may have been loosen and I may need to dissemble the iPhone to fix it...
