Unlock iPhone 3.1.2

It’s possible to unlock iPhone 3.1.2 but only if your baseband has not been updated to 05.11.07 or the newer baseband, you must create a custom firmware that uses the 04.26.08 baseband. The iPhone 3.1.2 update updates the baseband to a newer one that permanently blocks the software unlock. A guide on how to unlock iPhone 3.1.2 will be up once a jailbreak tool is released.
