There was an update to version 0.0.2 on ClickOnce today. However, based on my experience with it…
I would say do not install it!! It made my iPhone crash massively! After I installed ClickOnce and then closed Installer, my iPhone tried to respring (like it always does after installing an app) and it got stuck in a loop. I saw flashing white screens, scrolling white lines, and all sorts of other crazy things. I had to SSH in and delete the app.
So, I would hold off for now. If you already installed it…let me know how it went for you! ClickOnce is available through the iPhoneCake source.
