While replying to a tweet, MuscleNerd of iPhone Dev Team has confirmed that an unlock for iPhone 3G/3GS on 05.12.01 baseband will be released once Apple announces the new iPhone along with final GM version of iPhone OS 4. This announcement is expected to be made at WWDC 2010 so it wont be long before we finally get our iPhones unlocked on this baseband.

Unlock 05.12.01 Baseband

The said conversation between MuscleNerd and EmmanueGT is as follows.

@MuscleNerd will there be a unlock software coming out for the 3gs 3.1.3 baseband 05.12.01 when the new iPhone 4g comes out??

@EmmanueGT yep..so don’t sell or give away your 3GS 🙂 (at same time, remember not to accept Apple FW upgrades in future)

Also, DO NOT update your iPhone firmware to OS 4 once it is released in June. Doing so will update your baseband to 05.13 which may or may not be unlockable for some time. PwnageTool will of course be upgraded to take care of baseband when you are upgrading to iPhone OS 4.

In the meantime, If you are on iPhone OS 3.1.3, you can follow our step by step guides to jailbreak iPhone 3GS with Spirit here, iPod touch 3G untethered here, and iPad on OS 3.2 here. You can also use redsn0w 0.9.3, redsn0w 0.9.4, sn0wbreeze, PwnageTool 3.1.5 to jailbreak iPhone and iPod touch. Unlocking can be done using ultrasn0w or blacksn0w.

For iPhone 3.1.2 firmware, you can use blackra1n, PwnageTool, redsn0w, sn0wbreeze, ultrasn0w and blacksn0w to jailbreak and unlock your iPhone and iPod touch. [Thanks to @baseband for the hat tip via Twitter]
