how to unlock iphone 1.2

[m3thodandr3d]

What are you trying to do? Unlock iPhone firmware version 1.2 or 1.1.2? If you are on 1.1.2, simply upgrade to 1.1.4 with iTunes and use Ziphone for the unlocking process.

If you were talking about the 1.2 beta, you would need a mac with pwnage tool to perform the unlock.

Pwnage Tool only works for 1.1.4 if I'm not mistaken.
