Geohot’s iOS 4.x jailbreaking utility limera1n has been available for Windows since 10/10/10 and now, thanks to some handy coding, it is available for the Mac as well. The one-click jailbreak utility can be downloaded free of charge from; geohot does ask for voluntary donations to keep the project alive. If you give it a whirl let us know how it goes. Happy jailbreaking!
