This service is going to cost an arm and a leg, you know that, don't you. Repairs done by Apple themselves have never been cheap. I had a 2007 MacBook Pro once, and they said they'd charge me 300 euros to find out what's wrong with it, which I knew already, and then 1500 to replace the logicboard, if it turned out to be the graphics card, which it was. Seeing as that was more than I bought it for (second hand, mind you, but still) I kindly refused and bought a Dell L702x. Truth be told, though, having your iPhone repaired is still better than trying it yourself because, even though I'm not that incompetent, I've never managed to open an iPod without damaging it in some way.
