For some reason the 'Son of iFuntastic' application does not show up in the SpringBoard until you install another application with Cydia. If you see the iFuntastic app on your home screen, then this step is not necessary.
If you have one or more favorite applications, then please install at least one of them now. If not, I recommend Cycorder by saurik - it allows you to record videos with your iPhone!
Go to Cydia -> Sections -> Multimedia -> Cycorder and install.
or, on the iPod, install Cydia -> Sections -> Utilities -> Flashlight.
Click 'OK' when you are done.
iFuntastic will then start building its indices which may take 10 to 15 minutes.
No more interaction is required.
