I just recently purchased a 4th generation 8GB iPod touch and I would like to exchange it for a 32GB model. When I was at the store though, I bought a screen protector and had the man helping me put it on. Apparently it is supposed to b permanent, so will they let me exchange in the next 14 days with it on? I know that I can just sell it on eBay and use the money to buy the new one, br I would really like to avoid the hassle. Thanks for the advice!
