I have gotten my hands on a 8gb 3gs 5.1.1 with 05.16.05 baseband. I am trying to unlock this phone. Problem is the serial number is 84136.... so this phone was produced in week 36 of 2011. From what I read online is that if I downgrade to 05.16 ipad baseband I can brick this phone. Is there any way around this or should I just take my chances? Thanks.
