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

i use cydia personally but thats only because i find it simpler and cant be asssed wading through the stuff you have to do with rock also i heard better reviews aboout cydia.-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
I also want to know whats the downside with having cydia and rock if someone will let me know it would be appreciated

I use rock alot more then cydia, cydia has started to piss me off with the loading times.

For the most part, I use Cydia. I run it once in the morning, and then I'm set. No need to wait for Cydia to upload anymore.

Rock=Blows Big Ones.

i prefer using cydia

cydia for the win!

Cydia because of all the reasons posted before me.

Just put it in DFU mode and restore... and if you get new firmware you Press Shift+Control when you click restore select your firmware and your good to go.

Rock suck!
They have reviews system which is corrupt.
If they don't like a popular application they don't let anymore reviews on it.
They may be quick but Saurik cares about the community
And he is always bring in brand new stuff.
