    Default Downgrade to unlock

    Hey guys,
    I jailbroke via jailbreakme.com and unlocked via Cydia while still on 4.0 or 4.0.1, but then accidently upgraded to 4.0.2

    Should I be able to downgrade in order to jailbreak and unlock again?

    Sorry, I'm a bit confused with all the SHSH and TinyUmbrella talk.

    Thanks for your help!

    You have not mentioned what model iPhone you have, so I will assume you have a 3GS -as you posted in that section.

    Without a SHSH for 4.0.1 you cannot downgrade and jailbreak again.
    Unlock requires jailbreak (so no unlock either)

    If you have an iPhone 3G you can downgrade (or even jailbreak 4.0.2)

    Read up on this, then you won't be confused. The basic concepts have been explained hundreds of times in threads here and in other forums.
