Damn, 2.2.2. Thats old. U may have missed the train buddy. The latest iOS I seen that can be jail broken, the untethered way, is 4.2.1. No way u can get that iOS from apple servers as now the newest version is 4.3. The only jailbreak out for that is a tethered one using Snowbreeze on windows or Pwnage tool on Macs. The only possible way for u to find iOS 4.2.1 is to search for it on the web, then install n upgrade to that. When u do, go to Greenpoison.com and download the tool for either windows or Mac. Then install on ur PC/Mac, follow the directions(easy n simple) then jailbrake and ur done. Untethered jail brakes are the best as u can reboot as many times as u want n still be jailbroken. With a tethered jailbreak, u have to reboot Into jailbroken state therefore needing a PC/Mac everytime u reboot. That SUX and is a hassle IMO. Good luck!
