My choice is:
Bitesms (best app ever)
Callbar (second best app ever)
IconBounce (funny hehehe)
Springtomize 2 (great and saves a lot ov tweaks)
Sbsettings of course is a must have
Cydelete (uninstalls apps from Cydia directly from the homescreen)
Anyattach (makes mail app as it should be from scratch)
Photoalbums +
killbackground
Weetrackdata (a notification center app that tracks our data)
Bigify (to play with icon size and orientation etc)
Shrink (to replace bigify to shrink icons)
Nogoodnonews (or something like that To hide newsstand icon)
Infiniboard, etc and every tweak that makes us have 5x5 icons and enhanced folders etc
These are some of my favorites!
