First off, if you're hesitant about sending it in to Apple to repair, you need to get it back to the store pronto before your 14 day warranty expires. I say that because that's what ended up biting me in the butt- I didn't think it was any big thing, and waited too long.
On the other hand, I think it'd be beneficial to send it in to Apple if you can't just get a new one. I called early on Monday,a box was sent to me on Tuesday and I had it picked up on Tuesday. It was shipped pretty quickly through DHL, because late Wednesday, when I checked for repair status on here, it said they were ordering a part for the repair. Now, it doesn't say what part exactly, but it seems like something is being done.
I admit the call in general was not too helpful though. They are very good about not letting on that they have heard the problem before. Also, don't let them hassel you into trying lots of other things first- because I have tried all the things the person I spoke to suggested, and none helped. You will just end up hanging up, tryng these things, and then having to stay on hold for an hour again to talk to someone.
Anywho, I'll report back when I get mine back, see if it REALLY is fixed! Thanks for all of you who posted on here- it did seem to make a difference somehow when I spoke of it to the AppleCare rep.
