Cydia - much better
when I first JB my i, I installed Cydia based on a friends recommendation. I just reset to factory and did a second JB, this time installing Rock. Rock is nice with the rotation feature but, did not seem as simple to navigate through as Cydia.
Yes, it looks nicer. Yes, it loads faster. But I didn't like that it wanted me to login constantly or the fact that so many apps were pay apps.
all in all, it works. But Cydia is just easier to use and, seems to have more apps.
I am concerned a bit that apps I install using one package don't seem to show up on the other.. but if I blow up the phone I'll just start over.
so glad I JB though.. I hope Apple takes a cue and opens things up on the next gen iPhone.
