Depending on how convenient it is to get to an Apple Store, it can't hurt to ask. I have gone into our local store several times, and the answers are usually very customer friendly (that's obviously a problem - let's fix it). My phone had some display issues, almost certainly due to the fact that by living in my back pocket it was slightly bent. The first time I asked, they wanted to charge a replacement fee. I declined. A few months later they replaced it for free. To other factors to weigh - this is all Apple Care, and swapping out units is a pain, what with backups, etc
