The iPhone Dev Team has just released PwnageTool 4.1.1. This is more of a bug fix release which fixes issues for Mac OS X 10.5.x Leopard users.
This is our 2nd Obama-related post of the day, but hey: it’s not everyday you see the American president sign an iPad, right? Sylvester Cann (the dude holding the iPad) writes the following.
PwnageTool 4.1 has been released. You can use it to cook custom firmware files without the upgraded (2.10.4 / 05.14.02) baseband for iPhone 4, 3GS and iPhone 3G running on iOS 4.1 so that you can unlock it using the existing version of Ultrasn0w. This version of PwnageTool also supports hacktivation.
The iPhone Dev Team has finally released PwnageTool 4.1 which is based on recently released Geohot’s bootrom-based Limera1n exploit. This exploit enables this new version of PwnageTool to build custom firmware files for A4 devices like iPhone 4, iPad, Apple TV 2G and iPod touch 4G which was something, previously not possible.
The iPhone Dev Team has finally teased us with a screenshot of the upcoming PwnageTool 4.1 for all iOS devices. This new version of PwnageTool is based on Geohot’s Limera1n bootrom exploit which will allow us to restore custom cooked firmwares (without the upgraded 05.14.04 / 2.10.4 basebands) on almost all the current iOS devices, including: iPhone 4, iPhone 3GS (new bootrom), iPhone 3G, Apple TV, iPad and iPod touch 4G / 3G / 2G. This will enable all iPhone users to unlock using the current version of Ultrasn0w so that they can use the phone on any carrier they like!
Incase you were wondering why Geohot used a userland exploit from Comex to make Limera1n untethered, it was because he did not wanted to waste his untethered version of bootrom exploit which seems to be more powerful than the exploit used in Limera1n. Both Comex and MuscleNerd has confirmed that Geohot has in his possession a new untethered bootrom level exploit which can be used to pwn future iOS devices like iPhone 5 and iPad 2G for life.
The following step by step instructions are going to help you jailbreak iOS 4.1 on iPhone 4, 3GS, iPad, iPod touch 4G / 3G using GreenPois0n on Mac OS X. Support for Apple TV and iPod touch 2G will be added soon.
Chronic Dev Team has just released Mac OS X version of GreenPois0n tool which like the Windows and Linux version can jailbreak iPhone 4, iPhone 3GS, iPod touch 4G / 3G and iPad on iOS 4.1 and iOS 3.2.2 respectively.
MuscleNerd of iPhone Dev Team has teased a little video which shows off the upcoming PwnageTool in action. This new version of PwnageTool is based on Geohot’s Limera1n bootrom exploit which will allow us to restore custom cooked firmwares (without the upgraded 05.14.04 / 2.10.4 basebands) on almost all the current iOS devices, including: iPhone 4, iPhone 3GS (new bootrom), Apple TV, iPad and iPod touch 4G / 3G.
Mac version of Limera1n is now available for download. Even though the instructions for Mac are exactly the same as the one for Windows, I thought I would do the guide again for our Mac users who come here, searching for the Mac version of the instructions.
