So the other day I bought an iphone 3g-s brand new. So far I love everything about it. The one thing I noticed though it the sleep button (the button on top of the phone) seems to have a little play and slightly moves back and forth when you push it. Sometimes I can sort of hear it if I go out of my way to shake the phone but barely. It doesn't affect performance or anything, I was just wondering if this was normal for this particular button? Thanks!!!
