I am not I pod touch savvy. I have a question re: the ipod touch. I want to buy 8GB ipod touch through eBay because they are inexpensive. my hesitation are the following: 1. can a used device serial number be stolen?? 2. the battery inside has gone diminished or bad charge?? 3. if I enter my e-mail in the used ipod touch is there a way the old owner steals my passwords and e-mails? in addition to using it through the wi- fi internet through the router? they can look in through it? I want one with a camera. I don't care about condition. should I pay the retail price for the I pod touch or risk buying used and being compromised ?
