    I've been looking everywhere for a custom ipsw for my 3GS that is already jailbroken, so I can restore to 4.0 and have a jailbroken iPhone. Anyone want to point me in the right direction?

    Nevermind, disregard this. I found some but most people are saying if your 3GS is currently jailbroken with Spirit it will not work.

    At the iPhone hacks section.
    That is correct.
    Wait a few more weeks.

    We are not allowed to link to illegal downloads on this forum. Sorry.

    And, yes, custom firmwares only work on phones which have been "pwned" (that is, which have had their baseband modified to accept unsigned firmwares). Spirit is a "userland" jailbreak, which makes its modifications to the OS after it has already booted. Phones jailbroken using Spirit are therefore not pwned, and cannot be restored to custom firmwares.
