Hello. I jailbroke my ipod touch, 3.1.2, via blackra1n and it went successfully. For the past few weeks I've been tinkering around, adding new apps, themes, sounds, etc via CYDIA. I'm using cydia because that's all I hear that people are using. But, my friend let me jailbreak his ipod, and to test it out, I installed rock. I loved it because of it's speed, and modernized looks. Here's my problem. I already have cydia and a bunch of apps, packages, and themes from it. I want to try out rock, but I'm afraid I'll mess something up on my ipod. I was thinking of trying both at the same time, but I'm afraid there will be a compatibility problem. Also, I've been hearing that Rock is very unstable and screws up a lot of ipods/iphones. Cydia, rock, or both?? Thanks for your help.
