i have an iphone 3gs, I put my t-mobile sim in the phone and synced it up with itunes and it worked, my sister however put her t-mobile sim in and tried to connect to itunes and it wouldnt work, any ideas? the message i get is the phone is locked please enter passcode, but it wont let me enter the code on my iphone it just says emergency calls, however when i put my sim back in it worked fine, please help
also the phone is jailbroken, is it worth doing a master reset of the phone, installing the lastest software update and then getting an unlock the official way?
