Why are you still on 2.2.1??? you can jailbreak 3.0.1 now, its much better firmware.

If you are going to stay with 2.2.1, check out these tutorials for jailbreaking. But as said above, it's better to move to 3.0.1 now.

I used a mac and pwnagetool.

I backed up the phone, then downloaded the new "iPhone1,2_3.0_7A341_Restore.ispw" file. Ran pwnage, created a custom ispw and then restored the phone through itunes to that custom firmware. After all that, I just restored from a backup, and voila, jailbroken 3G running 3.0 software
