Ok a work colleague of mine has asked if i can try to unlock her phone, a nokia 6230. Having had a few phones unlocked by you kind people myself i thought i'd seek your help. I'm not sure what network she is on, i think it is t-mobile and her imei number is 353767005765349. I have tried trycktill and after trying a couple of codes to no avail i ended up with the message 'restriction cannot be removed' i didn't try 5 codes incase anyone suggests that. Can anyone help?
