I've done international sales on my Iphone 3G and the whole time I was worried. Eventually everything was fine, but I told myself I wouldnt do it anymore and just wasnt worth the risk. The reason for is Paypal cannot have confirmed addresses internationally and as a seller that is very important because thats your only protection. When you sell a phone on Ebay, the best form of payment is Paypal. When you use Paypal, as a seller to be protected from fraud. Your buyer must be registered with Paypal and a VERIFIED BUYER and also the address where you ship it must be a CONFIRMED ADDRESS. If you mail to any other address and for some reason the transaction was fraud the whole time, guess whose out? YOU!!!!
Basically if I were you, I would not sell it to that person. Keep it within the states and follow the instructions I told you/ Paypal requres! Good Luck. Resell it on Ebay and make sure you have a verified buyer and mail it to a confirmed address only, anything else DO NOT SHIP OR SELL!
Oh yeah, shipping is not cheap either.
