If this post is not in the right section, please move it elsewhere. I got an ipt3g with apple standard warranty, which will expires on April 2011. I went to an Apple Authorized Service Provider (AASP)in Vietnam and request a repair, they said I will get another new ipt3g but it takes 1 week ! I have to go to the US few days later so I prefer to do it in US. Luckily, ipt4g will be released next week. Can I exchange my defective ipt3g for ipt4g for free or with a small fee (approx. only)at Apple Store ?
