I actually got a replacement after my silent switch broke off. They gave me a new one and it didn't sync to my computer at all, then they just gave me the one I currently have and the silent switch is very loose when in the silent position. I took it back saturday (second day of the 3gs release) the store was crazy and I explained the problem to the genius bar and the gentleman took out his phone and tried his and said 'wow mine does that too' then he went in the back and apparently 'tested' this on several other employees who had an iPhone. Then told me that it was common and there was nothing he could do that would fix it because if he gave me a new phone that too what most likely rattle and be loose. It is really bothering me, especially since every new 3g and 3gs I picked up in the store didn't rattle or have loose silent switches. Should I take it back to apple, call, or go to AT&T?
