Just jailbroke my iPhone 3G, and have been poking around in SSH and whatnot. I found two apps called "FieldTest" and "DemoApp". I sort of just ignored them for a while - but then I installed AppFlow, an application launcher, from Cydia. I was messing around with that and saw those two apps again. So I launched DemoApp - my screen went black, nothing happened, and I pressed the home button and went back to the home screen. But all my icons were in a messed up order. Any ideas what these two apps are? edit: Crap, I'm stupid and didn't search first. Mods, delete this if you want.
