    Back up your phone. Update it to 4.0.1 w/ iTunes. Open safari on the phone. Go to JailbreakMe. Swipe to JB. Open Cydia and make sure to buy something from one of the devs. (infinifolders, or signal) for hooking u up w/ the free Jailbreak. Restore your backup from iTunes. **not the restore button!!!*** right click ur phone in iTunes and select back up from restore. There are several guides on this process. Btw.

    what he said except restoring from a backup can cause problems, so if you dont realy need any texts, emails etc etc. then I would set it up as a new phone so you have less chance of having problems
