Cydia versus Rock Help me understand this. I was under the impression that both applications does the same thing and it's a matter of preference which you like better. However, it seems like if you purchased an app from Cydia, and later on, you download the same application from Rock, any registration, validation, etc. that you have purchased for the application won't work. In other words, you have to download the same app from Cydia again versus Rock. I guess the question is, between the two, I have to technically keep both but what are the advantages between the two? Furthemore, any way to completely just move over to Rock (just better UI).
