The iOS 4 Upgrade, Jailbreak, and Unlock FAQ [Updated 8/2 - Updated Flow Chart]

[tails-4]

So ive got a question that might help a few people out....

Im currently running an iPhone 3GS on 3.1.3, which is jailbroken with Spirit.
Is there anyway to upgrade to 4.0, without loosing the jailbreak?? (i.e. without having to re-jailbreak??)

ANY help always appreciated
