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?

Thanks for the reply, no she doesnt. however it doesnt give her the option on the phone to enter a passcode, it will only allow emergency calls,

we have just put the phone in DFU mode and restored it so it has removed the jailbreak and its still working ok with my sim, havent tried hers yet,

any ideas on how to remove my itunes account from the phone so she can use it with hers?
