I just sold an iPhone 3G and 3GS on eBay and i have received payment and i have shipped to the address listed on pay pal. The 3G i shipped to NY has been received 4 days ago but the buyer has not responded to my requests to leave positive feedback so my funds are released. The 3GS has been shipped to Indonesia and it hasn't been received. Im getting nervous Paypal says im protected but only if i had a delivery signature which i did not get, only delivery confirmation. Now after 13 days when my payment clears, how can the buyers scam me? Will they request to reverse the transactions or dispute it somehow like they didn't receive the item? Any help would be appreciated.
