well i have a 3g, and a 2g but i never had a problem jbing either one until now, everytime im about to jb my 2g quickpwn says that i dont have the right firmware but i updated my 2g to 2.2.1 (but i used a different pc to jb my 2g before now im using my laptop) so i did a full restore on my 2g from the original pc that i used so i think im stuck cause im not sure what firmware its on. can some one help me, i just want to be able to use my 2g as a ipod now. no need for anything else maybe a few cydia apps and a different theme but other then that i rather use it for an ipod
