Couple of days back, iPhone Dev Team released PwnageTool 4.1 for Mac OS X based on Limera1n's exploit to jailbreak all iOS 4.1 devices. Now, they have merged Limera1n's exploit into Redsn0w too to be able to jailbreak iOS 4.1 on iPhone 4, iPhone 3GS, iPhone 3G, iPad and iPod touch. Moreover, this version brings custom boot logos and the ability for Windows users to restore using custom firmwares created by PwnageTool.
- custom bootlogos for iPhone3G/iPhone3GS/iPod2G users (with qualifying bootroms)This tool supports both Mac OS X and Windows. The instructions to jailbreak your device are the same to the previous ones, so you can follow the steps posted here to jailbreak your device using Redsn0w but don't forget to download Redsn0w 0.9.6b2 below.
- an option that implements the “DFU” button in PwnageTool. This button (which you can use from Windows) lets you prepare your device for a custom DFU. Even if you’re purely a Windows user, you can get a trusted friend to run PwnageTool over your IPSW to create a custom IPSW. You can now install that custom IPSW on your own Windows box, after you run this redsn0w version.
