Jailbreak and Unlock iPhone 3G iOS 3.1.2 with Baseband 05.12.02

• We can Jailbreak iPhone 3G with 3.1.2
• Unfortunately, current Ultrasn0w is unable to Unlock the Baseband 05.12.02
• My old (USA-version) iPhone 3G has become an iPod Touch only (for the time being).
• The good news is that Sherif Hashim tweeted that the Unlock solution for 05.12.02 and 02.10.04 will only be release after iOS 4.2 is out. Most probably to avoid Apple closing the hole.

UPDATE:

• Use this Wizard to check whether your iPhone can be Jailbreak or Unlock--> Ultimate Jailbreak & Unlock Wizard
