The iPhone configuration utility is pretty easy to use, but it obviously requires that you have a Mac or PC at hand. It would be easy to write a web app that allows you to create/download custom configuration profiles2, but I wanted to see if I could do it just using Pythonista, without requiring an internet connection.

Very interesting script by Ole Zorn (of Editorial fame) that hosts a webserver on your iPad to host and install custom webclip icons.
Cool stuff.
