Hey,
I like the app idea of posting what your faves are for the AppStore, so here's mine for Cydia on a jailbroken phone.
Intelliscreen ( http://www.intelliborn.com/products.html )
This gives you the ability to put calendar, sms, email, weather, news, sports, etc... on your lock screen.
Winterboard ( http://www.saurik.com/id/9 )
Themes... this can convert the whole iPhone experience into something custom.
Stacks ( http://www.tuaw.com/2007/10/20/stacks-on-the-iphone/ )
Old link, but gives you the idea... it adds a Stack to the bottom right of your iPhone's Dock, and you can add apps to it for a quick launcher, of sorts. Super userful!
iPhoneModem ( http://www.iphonemodem.com/ )
Basically, just what it says. It tethers your iPhone to your computer so you can use your internet connection with your computer. Really drains the iPhone's battery, but I love being able to use this when I absolutely have to edit some stuff and put it online.
There are more, but those are my absolute must haves.
