    I did this on my friend's iPad.

    Back up in iTunes
    3.2 > 4.2.1 using iTunes

    Jailbreak using greenpois0n
    Install Cydia using redsn0w

    All the cydia apps were gone, so I recommended using AptBackup or similar. However, going from iOS 3 to 4, many of the Cydia apps were no longer needed. Such as backgrounder.
