I personally have both Rock and Cydia. For those who use Icy should either go to Rock or Cydia.

Rock sucks haha. Cydia is better, but thats probably cuz I jailbreak 3.1.3 so its faster.

Rock is horrible, Cydia all the way.

Rock is awesome. i made it have everything cydia has and i upload stuff to rock!

I like Rock more because it is faster, but I use cydia for items Rock can't download. (Which there is little Rock can't download)

i have cydia and rock rock is faster but i use cydia a lot more than rock

Other way around for me

I have both Rock and Cydia, but I use Cydia much more frequently.

i have both, but i use rock a lot more, it seams easier than cydia.

rock is a cydia app lol
