Apparently, there is an unofficial version of PwnageTool out in the wild which can jailbreak iPhone 3GS (with old bootrom and already pwned on 3.1.2) on the latest iOS 4 firmware. The creators of the original PwnageTool has confirmed that this version has been modified and redistributed without their permission, and most importantly, it doesn’t patches some important files which are required for the ultrasn0w unlock to work properly.
Redsn0w has been updated to bring jailbreak support for the newly released final version of iOS 4 for iPhone 3G and iPod touch 2G. Available for both Windows and Mac, redsn0w jailbreak tool additionally also enables options for multitasking and background wallpapers on iPhone 3G and iPod touch 2G which otherwise are disabled by Apple.
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.
Redsn0w 0.9.5 has been updated! which brings long awaited support for Windows users to jailbreak iOS 4 GM (formerly iPhone OS 4) on iPhone 3G and iPod touch 2G. Like the last release, this update also includes optional support to enable multitasking and wallpapers on iOS 4.0 on iPhone 3G and iPod touch 2G which otherwise are disabled by Apple.
The guy who previously unlocked iOS 4.0 Beta 4 (formerly iPhone OS 4), PwnageTool bundles for iPhone 3GS on iOS 4 and Blacksn0w RC2 patch for iPhone 3.1.3 is now back with a new patch, which makes Blacksn0w unlock compatible with iOS 4.0, provided that you have preserved your baseband to 05.11.07 using PwnageTool.
The latest version of Redsn0w brings full support to enable multitasking and wallpapers on both iPhone 3G, and iPod touch 2G, running iOS 4 which otherwise are disabled by Apple, citing performance issues. We have already posted full detailed guides on how-to enable multitasking and wallpapers support on iPhone 3G and iPod touch 2G manually. If those guides are too long or complex for you, you can now use the latest version of redsn0w which gives you a one-click option to enable these options with ease.
We did inform you about PwnageTool bundles which were released yesterday to jailbreak iPhone 3GS on iOS 4.0 (formerly iPhone OS 4), while preserving your baseband on the older 05.11.07 or 04.26.08 so that you can unlock it using ultrasn0w or blacksn0w. We got lots requests via twitter, facebook and email for full instructions on how to patch the existing version of PwnageTool so that it can work with iOS 4.0 GM release. And so here are the complete set of instructions for you to get it to work.
The GM (Gold Master) release of iOS 4 for iPhone 3GS, 3G and iPod touch 3G, 2G has made its way on the popular file sharing and torrent sites. Unlike all the previous Betas, this release actually doesn't require registered UDID, and you can restore it on a Windows machine too but it will be pointless as for activation, you will still need iTunes 9.2 Beta which is currently only available for registered developers on Macs.
Since Apple has renamed iPhone OS 4 to iOS 4, we thought we will update our jailbreaking guide for iOS 4.0 for both iPhone 3G and iPhone 3GS. The redsn0w 0.9.5b4 which was released for iPhone OS 4 Beta 4 (now iOS 4) will need an update to work with this version of iOS 4. But the instructions to jailbreak would remain the same. We will let you know as soon as an update is available.
