It was only a few days ago that we brought you the exciting news that iPhone Dev Team and their rock star lead MuscleNerd had been working covertly on a way to allow users to downgrade the baseband on their iPhone 3G and 3GS from 06.15.00 to a prior one with full unlock and GPS support. This may not be something which some of you actually require, but for those unfortunate ones who had to update to the iPad baseband to get an unlock last year, it is certainly a nice welcome, especially with the launch of Apple's new Maps service in iOS 6 that makes extensive use of the device’s GPS capabilities.
Last year, company by the name of CutYourSim caused a mixture of excitement, confusion, and subsequent disappointment and cynicism when it released a permanent unlock procedure - only for the service to be abruptly halted once Apple caught wind of what was occurring.
The newly released Sn0wbreeze 2.4 supports Ultrasn0w unlock for iPhone 4 and 3GS users (old basebands only) which otherwise happens to be broken on the latest iOS 4.3.1 firmware.
As we reported earlier, both PwnageTool 4.2 for Mac and Sn0wbreeze 2.2 for Windows are now available which can preserve baseband, and jailbreak iPhone, iPad and iPod touch on iOS 4.2.1 firmware.
Redsn0w 0.9.6b5 has just been released which can jailbreak and update iPhone 3GS & 3G baseband to 06.15.00 so that it can be unlocked using the newly released Ultrasn0w 1.2.
As promised, the iPhone Dev-Team has released the necessary carrier unlocking tools which can unlock the latest iOS 4.2.1 firmware on iPhone 3GS and 3G on basebands later than 05.13.04. Since iPhone 4 has different baseband OS, It'll take a little while longer for the Dev Team to unlock it on the latest firmware.
Last week, we published a post where we told you that the unlock for iPhone 3GS with the latest 05.14.02 baseband was currently not being worked on as both the Chronic and iPhone Dev teams were focusing on iOS 4.1 jailbreak (based on SHAtter exploit). With respect to that, we’d like to present a piece of good news to our readers: that of an 05.14.02 baseband exploit!
The newly released iOS 4.1 for iPhone 4, 3GS, and 3G features new baseband which is currently not unlockable using the current version of ultrasn0w. But if you upgrade (while preserving baseband) and then jailbreak iPhone 3GS on iOS 4.1 using PwnageTool method posted here, you can unlock your phone (iPhone 3GS) using the existing version of ultrasn0w. Also, if you upgrade your iPhone 4 (while preserving baseband) on iOS 4.1 using the method posted here, you will be able to unlock your phone (iPhone 4) as soon as the new jailbreak tool is available for download.
