As we were expecting, Apple has just released new updated version iOS 4 4.0.2 for iPhone and iOS 3.2.2 for iPad. This has been done to patch up the jailbreak for iOS 4.01 and iOS 3.2.1 that was done earlier by JailbreakMe.

Accidental update to iOS 4.0.2 / iOS 3.2.2, will make it impossible to jailbreak and unlock straight away until a new tool comes handy. The only way you can jailbreak again will be by downgrading back to iOS 4.0.1 or iOS 4 for which you will need your SHSH blobs, so better save them now.

To save SHSH blobs, follow procedure posted here.         [Via Redmond Pie]
