Not much for installing a million App Store apps (I find all the functionality I need from Cydia), I too have a list of my top 5 favorite AppStore apps.lol
And there is one more, but ya only asked for 5.......not 6
But I would give up literally any other app(from the AppStore that is!) on my iPhone then give up one of these...........I could maybe do without Cloud2go, and keep Tanso DLM.;p
