JB it now on 3.1.2 with redsnow.I have an iPhone 3GS that was jailbreak before but it have the iOS4 installed. I manage to downgraded to 3.1.3 and also downgraded to 3.1.2. Someone can point me to the right direction if I can jailbreak this phone with the downgrade I did. Its officially a 3.1.2. Any help will be appreciated.
