But i tried using greenpoison and its not working correctly.....is there another program i can use? am i doing something wrong? Please bare with me

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.

how can i downgrade from 4.2.1 after ive already jailbroke? i didnt think i would be able to because im on the iPad baseband now 6.15......and also i was afraid i wouldnt get alot of features by downgrading the firmware?

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.
