The other day John Gruber linked to a particularly interesting little web app that works like a charm with iOS 4 and its folders. Glyphboard, as it's called, is a board of symbols that you can copy to the clipboard to then use in your texts, emails and so on. It's a useful app if you like smileys, and it can also be used to enhance your folder names.
To give it a try, just point your iDevice to Glyphboard (link). You will be required to save it to your home screen via the (+) button at the bottom. Here it is on video:

***Update
I'd never thought of it, but you can actually push the craze much further by using emoji as pointed out by bramvera (thanks!):
