I recognized that Apple Store UK sells unlocked iPhones 4 at reasonable prices. However, problem is that they only deliver to UK addresses. But there is a service called borderlink that gives you a free UK-based address. So you could order the phone from apple store and give this address to them. When it arrives at borderlinx they will send it to you. So this would be a good way to get genuine iPhones directly from Apple for selling on eBay. However, what I am asking myself is, are there any limitations. That means, how many times can you order phones to one and the same address?
