Just got a 2g Ipod Touch. I want to jailbreak it. I tried using Blackrain to do it, it goes all the way through and reboots, installs the blackrain app. After all of this, I tried going into Itunes to add some jailbreak apps that I have, but whenever I try to sync my apps, it fails on the jailbroken apps and gives an Unkown Error. Does anyone have any ideas as to what I might be doing wrong? I installed Iphonebrowser after doing the whole blackrain thing, and at the bottom of the program it says "Iphone is NOT jailbroken", says its missing the acf2 something or other, I cant remember off the top of my head. Shouldnt I be able to use itunes to add jailbroken apps to my itouch after I run blackrain? I just want to jailbreak my ipod, and blackrain seems to be the way to do it, I've gone through the proper steps, I just want to get it working so I can install these jailbroken apps and make customizations, install what I want, but its still not working. Should I be using something other than itunes in order to upload these apps? Any ideas or suggestions would help. Also, what is the point of Cydia? What is it used for? I know its for installing software, but what specifically?
