Where to find custom ipsw for 3GS & iOS 4?

[jmack549]

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.

Darn.

That is correct.
Wait a few more weeks.

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.
