Hey guys, lately I've been using rock instead of cydia, but I made the stupid mistake of deleting cydia. I didn't think I'd need it until recently. Lately I've been getting some error. Now I can't install anything. I tried reinstalling rock and everything. If I use blackrai , will it completely rejailbreak my iPod or will it just install the blackrain app? I haven't been in the scene for a while, so I'm a bit lost. Many thanks, A.O.
