Hi guys. I have 2 iphones 4S and 1 3GS. I use them everyday and cant be more happy. But now im facing iphone 5. I found them on eBay (also those 3 phones were bought on eBay) for 600$ shipped. BUT they have bad ESN. Just 1 short answer as googling it couldnt clarify me. Can i use them outside US Ex in Albania with GSM mobiles. Im handy with jailbreak / flashin / Gevey etc. Thank you !
