I had a 3g jailbroke for a while and didn't really enjoy it because it was so laggy....it really bothered me and unjailbroke it and never wanted to go back with the 3g....Now I have a 3gs and wanted to know will it be a small diffrence or a big diffrence with it jailbroken than the 3g...I want to do it again but I hated it on my 3g..is it better on 3gs?
