So, about 3 weeks ago I sold my iPod Mini Silver 6GB on eBay for 247. It included a Mini iSkin and was in flawless condition. I shipped it out in the original box (very secure and tight packed). Just yesterday I emailed teh buyer and asked him to leave feedback. He tells me that the iPod was cracked, and he was going to file a complaint with eBay (3 weeks later). I find this VERY VERY hard to believe, considering this happened 3 weeks later, the iPod shipped in APple's packaging (very sturdy). What should I do?
