Its here! This is what you all have been waiting for!! Ultrasn0w 0.93 has been released to unlock all iPhones on the latest 05.13.04 (on iOS 4) and 05.12.08 (on 3.1.3) basebands. The guide for unlocking is exactly the same as posted here, except for the Cydia repo which this time is: repo666.ultrasn0w.com. Follow that one until we update the post here! Stay tuned for more!
We have been hearing about this one aren't we? but what we have now is final confirmation. According to the member of iPhone Dev Team, full carrier unlocks for iPhone OS 3.1.3, and iPhone OS 4.0 will be released this month once Apple has released both the final version of iPhone OS 4, and the next iPhone 4G / HD.
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.
Folks behind the Gull1hack tool are also said to be working on a new unlocking tool dubbed Blacksn0w V2 which according to them will ultimately unlock the new iPhone 3.1.3 05.12.01 baseband on iPhone 3GS with new bootrom. I for one wont believe them until they come out with more proof of concept screenshot and videos.
A working exploit has said to be found by an iPhone hacker named Sherif Hashim. The exploit was sent to iPhone Dev-Team and they have confirmed that it is working but have not given any ETA on when or if they are going to release a tool which is going to unlock iPhone 3.1.3 05.12.01 Baseband for iPhone 3G and 3GS. Maybe they don't want to waste this all important exploit for this minor update and instead will use it when the major update such as iPhone 3.2 or iPhone 4.0 is released with the next-gen iPhone 4G.
