My friend purchased 10 iPhones 3gs 32gb from www outrightwholesale dot com a week ago and they seemed to be good. We opened one box and connected it to iTunes and it came back registered with Apple. They were all unlocked but not with dev team software, my buddy tod me that they were factory unlocked, what does that mean? Can I use any sim card in it overseas? I am thinking about starting a business dealing in iphones and the prices that they are selling at, I can see there is a bit of profit to be made. I just need to know if the factory unlocked version is the same as what I would buy at Apple store and they can be used overseas without any complications. I dont want to sell anything to ppl that are going to be mad at me. Thank you in advance.
