Sn0wbreeze project, redsn0w recently added support for a tethered jailbreak of iOS 5 beta 6. While support for the iPad 2 still isn't in the mix, the latest version -- 0.9.8b7 -- adds additional support for Apple's latest beta on the original iPad, and the folks at Smash iPhone have provided a tutorial for those who move to the beat of a different drum. While redsn0w supports a tether-free solution for iOS 4.3.3, if you want to partake in Cupertino's freshest fruits, you'll be required to connect your phone or tablet to your computer whenever you power up the device. Also, while download links for iOS 4.3.5 and 4.2.10 are in the tutorial, if you're not a developer, it'll be on you to scrounge up the latest beta. Best of luck with the foray.
