The official ultrasn0w unlock is now available for iOS 4 which works on all basebands including 05.13.04 and 05.12.01 on iPhone 3GS and iPhone 3G. Since there is no jailbreak available yet for iPhone 3GS with new bootrom, you cant unlock it as even though the baseband is unlockable. This is because unlock relies on jailbreak. So if you have an iPhone 3GS with new bootrom and you rely on an unlock, it is best to avoid iOS 4 (formerly iPhone OS 4) for now.

In a reply to a tweet, MuscleNerd of iPhone Dev Team has confirmed that iOS 4 (formerly iPhone OS 4) is confirmed to be unlockable, and probably so is the yet to be released iPhone 4. What they have actually got this time around is a new exploit for the latest 05.12.01 / 05.13.04 basebands, which they have been saving for months for a major new update – the time for which has now come.

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.

The title says it all. The popular unlocking tool for iPhone 3GS, 05.11.07 baseband on iPhone 3.1.3/3.1.2 has been successfully ported to work with the latest iPhone OS 4 Beta 4. This port is based on the binaries provided by msft.guy and the original blacksn0w unlock by Geohot.

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 for iPhone 3.1.3 on 05.12.01 baseband is here, but not in the ideal way you would have liked. Some folks over at a Turkish shop have managed to successfully unlock an iPhone 3G, on OS 3.1.3, running 05.12.01 baseband via a hardware flash. They have also shot a 10 minutes video which shows the whole process of re-flashing the baseband back to 04.26.08. Video after the jump.

Developer of GreenPois0n – p0sixninja has just posted a long detailed post, clearing out the confusions that many of you may be having regarding GreenPois0n, Chronic Dev Team and their authenticity. According to him, they have have found an exploit in the latest iPhone 3.1.3 firmware which will be able to unlock and jailbreak iPhone 3GS (new bootrom), and iPod touch 3G untethered. All they are now waiting is for the iPad with iPhone 3.2 to hit shelves on April 3rd.

If you accidently updated to the stock iPhone OS 3.1.3 from iTunes and are locked out, you maybe in with a luck as an unlocking tool is said to be out soon. George Hotz has confirmed via his twitter account that he has a working exploit which can unlock the latest 05.12.01 baseband which Apple bundled when they released iPhone 3.1.3 for iPhone and iPod touch earlier this month. While no ETA was given, judging by his tweet, it may not be too long before we get the updated version of blacksn0w which can unlock 05.12.01 baseband on iPhone 3.1.3 firmware.

Well it looks like Apple has started banning iPhone hackers from the iTunes App Store. Sherif Hashim, the iPhone developer and hacker who recently found an exploit in the latest iPhone OS 3.1.3, which could enable the unlock on 05.12.01 baseband for iPhone 3GS and 3G devices has been banned by Apple for the so called “security reasons”. This is what Sherif gets when he tries to access App Store from his iPhone.

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.
