BigBoss has released iOS 5 semitethered jailbreak for iPhone, iPod Touch and iPad. According to BigBoss official blog:
“The semi-tethered jailbreak will allow you to reboot your iDevice, but with limited functionality. It is enough that you are no longer stranded, and you can use your phone, text, and many other features. This is just until you get access to Redsn0w again to “just boot tethered”. Once you do that, you’re back to fully functional state.
You can follow the steps below to perform semitethered iOS 5 jailbreak on iPhone 4, 3GS, iPod Touch 4G, 3G and iPad 1.
