I used to have OS3 on my 2g iTouch, but I updated to iOS4 just yesterday and jailbroke it again. But when I downloaded Five-Column Springboard and Five Icon Dock, it went to safe mode and I had to re-jailbreak it. Today I tried to download Five-Column Springboard again, and it did the same thing. Now i HAVE TO RE- RE- jailbreak my itouch! Is there any way to get five columns on iOS 4 firmware????
