I bought an ipod 3G this summer off amazon and it has been working fine until about a couple of weeks ago. Lately my battery has been draining really fast and I have checked all the wifi settings and push settings and they seem fine, it is not JB by the way. Can I return it to an apple store? Would there be a problem since I bought it from amazon? Once I bought it I registered it online too. If they replace my ipod would it be a 3G or a 4G model?
