also some must have apps are,
Winterboard for your themes
Sbsettings, very handy toggle for your settings where you run your finger cross the clock and can tun off settings easily.
MyStrings, you can change all the settings like slide to unlock and every other text you can think of like turning it off or slide to answer anything you can think of and fake carrier names and wifi/3g icons
Infini dock/folders to put as many icons in the dock and as many folders and files in the folders as you like.
another good one you can install while jailbreaking is Animate, allows you to have animated boot logos.
and barrel, changes the way the icons scroll in and out, you can have it like a cube and more..
also phil announces some pretty good cydia apps if you decide to jailbreak.
