Hi, I just jailbroke my 2nd gen ipod touch with 3.0 OS using redsn0w, it worked fine as per the steps followed and this was my first time jailbreaking it. After the jailbreak, I could see Cydia and Icy in the menu, and on opening Cydia it asked me to install essential upgrades, once i started that though it gave me an error, and didn't install the update.. hence I can't download/install any other apps thru cydia like SBSettings or Winterboard.. please help ? I also tried jailbreaking it all over again, but that didn't work either. Any advice? Please help!
