Currently I am unlocked with IOS 4.01 baseband 05.13.04. I want to upgrade it to IOS 4.2.1 and I would like to know if I can unlock it using pwnage tool 4.2 and custom firmware? I would really appreciate it if you could help me. Thanks! Fri, 4 Mar 2011 08:08:56 +0000 http://blog.iphone-dev.org/post/3314130778#IDComment132325037
