    Are you on Windows or a Mac? Which firmware are you trying to JB to? IMO anything beyond 3.1.3 on a 3G is not a fun experience. The Greenpois0n tool is for 3Gs and iPhone 4, you have to use Redsn0w. You can find instructions here, it is not a tethered JB for the 3G. I might be wrong it's been years since I JB a 3G but I'm pretty sure I'm right.

    If I were you I'd definitely look into downgrading to 3.1.2 or 3.1.3. Using 4.x on a 3G is really asking for lag, and a lot of the features of 4.x you can get via jailbreaking the faster 3.x firmwares.

    I also agree with Massie like I said originally anything beyond 3.1.3 on a 3G means you'll have to put up with the lag. Did you enable any of the things in the JB? Multi-tasking, Wallpaper if you did redo the JB and don't enable any of them. If you want to have your wallpaper use Winterboard.

    IIRC, the 3G didn't use SHSH blobs for anything before iOS 4.0 ( and even with 4.0 it was a different kind of SHSH blob than something like the 3GS or the 4 ). You should be able to restore to 3.1.3 and have it work, though you'll definitely get an error restoring since you'll have a newer baseband version and that cannot be downgraded. You'll have to work out those errors ( use iRecovery I think to kick out of restore mode ) but the downgrade SHOULD work.
