Hey so I brought my american iphone 4 4.3.3 to Germany. I jailbroke it using pwnage and cydia loaded, so i downloaded ultrasn0w. So, it should be unlocked right? wrong! I tried to put in a prepaid microsim in the german vodaphone shop and it wouldn't work. we tried the microsim in other phones and it worked with them. Does anyone else know what I can do to keep my iphone? I am out of ideas... short of selling the thing on ebay and buying an unlocked one....
