Available in Cydia today is a fun little application that display quotes on your locked screen. This is the description of the widget by its author, Allen:
Entertain yourself and your friends with famous quotations everytime you go to your lockscreen. This widget for WinterBoard contains hundreds of quotes and each time you lock your iPhone/iPod Touch, a new one is displayed. Works on top of other Lockscreen themes.
While “entertaining” me and my friends with this widget sounds a little too much, I think it’s a really cool app to have. It just makes your iPhone look a little smarter…
One thing I’d like to be able to do is add my own quotes. Maybe for future releases?
