I know you can unlock an iPhone 4 with ultrasn0w but I need to JB my phone to do that and i'm not a fan of JB. Is there any other way? Or can I at least unlock with ultrasn0w then remove JB and it will still be unlocked?
I suggest you can approach Simpleunlocking.com and specify the country,locked network of iPhone4.Based on the availability you can get the permanent unlock service along with free instructions.
