The always-at-work jailbreaking specialists from the Dev-Team have already released an updated version of their popular jailbreaking tool redsn0w for jailbreaking in tethered mode the newly released iOS 5.1…but only if you have an iPhone 4, iPad, or iPod touch. Apple’s devices like the ipad 2 and the iPhone 4S, are still impossible to jailbreak.

But there are more ‘bad news’: if you’ve diligently saved your SHSH blobs via TinyUmbrella before upgrading to iOS 5.1 thinking that you may have been able to downgrade to an older iOS 5.x firmware, it’s impossible.
Therefore if you want to keep your iDevice jailbroken, don’t upgrade to iOS 5.1.
