This one is cool, is so ol' school, I actually had to add "star" (*), and "pound" (#) to the keypad.
Works great, and even has realistic push button activation.
Just upload this folder, SSH into your iPhone, then place it in private/var/stash/Themes, right into Winterboard.
Then, go into Winterboard, click "REAL OLD", and then let it restart, and you'll be on your way to the ol' school days.
Have fun,
Later,
