I recently upgraded from my iPhone 4 to the 5, but I'm having an issue with the screen wobbling when I hold it to my ear. It makes this clicking noise (sort of like the Blackberry Storm is supposed to). It happened on both my original and the replacement, which makes me feel like this phone is really cheap. It also came with a scratch, which I've read about in other places, although I was willing to let it go. But the screen moving around like this makes me worry that it's not going to last through two years of use. Is anyone else having this issue?
