This is an issue that I've had before when I was installing Rock. So after hearing the major issues of Rock and that I can use an app to boost the speed of Cydia, I decided to uninstall rock and re-install Cydia. I've installed Cydia via Blackra1n but the icon isn't showing up, thus saying that I've not installed Cydia at all. I had to wait 3-5 days before the Rock icon show up and I don't want to wait another 3-5 for my Cydia icon to show up so does anyone have a solution to this? Thanks in advance. EDIT: Just installed it again via Blackra1n and the icon still hasn't shown up.
