How to delete/uninstall an iPhone app

I'll try not to write too much about the devdaily website, but a friend of mine runs it, and I've helped him with some things from time to time.

One thing I wrote was this short iPhone tutorial on how to delete (uninstall) an iPhone app. I found out how to delete/uninstall an iPhone app quite by accident, and that's when I came up with this tutorial.

In a related note, you basically do the same thing to move an iPhone app icon.
