I just jailbroke my iPod touch 2G (MC model) and, as most people, can't get Loader to work. So I tried using redsn0w, but that won't do anything with my iPod model. So I used iPhone Explorer to install a copy of Cydia.app that I had laying around. Didn't work. So I used ar vx -x to get everything from the deb for it, and put it on the device. Cydia still isn't there. Is there any other thing to do?
