I finally got my 3G on Thursday. Today i've discoverd a pin prick like air bubble on the back plastic. Now I know I haven't done anything like drop it. I did put it in my pocket last night and I was "out" but my pocket was empty and I did not drop it. If I had dropped it I would have expected a bigger mess than a pin prick bubble. I'm confused and wonderd if anyone else has this on there phone??
