I have an unlocked iphone 4 and up until yesterday when I try downloading a free app or updating my current apps it asks for my billing infornation and after I put it in, it tells me that my security code is wrong... when it's not.
Can someone tell me how to fix this please?!
I just tried restarting it and that didn't seem to work..
I also plugged it into my laptop and synced it with itunes and that didn't help either..
