That would be great. Then I could get my jailbroken apps back. I sold my 3G and bought a 3GS on ebay that was already updated to 3.1.3.Mind me correcting myself and others?
OS 4 has been jailbroken already. Dev Team keeps under wraps (just like Apple secrecy) the new bugs and exploits they find. Pay off is that now, we have a working OS 4 jailbreak.
