Apple just released iOS 4.0.2 and as expected, they have patched the Jailbreakme.com bug that jailbreaks your iPhone on iOS4 OS. If you still care about your jailbreak and all the goodies that comes with it, DO NO UPDATE!
There is really no need to update from 4.0.1 to 4.0.2, there isn’t any change other than this patch.
