You guys really need to buy Titanium Backup Pro (if you haven't already) and backup every app (user and system) on a regular basis. I'm running 1.5 and "Files" isn't in there. So I simply fired up TiBu and restored the app. Took all of 5 seconds. Just sayin'. Don't depend on Devs to keep the apps that you like. It's their ROM, not yours.
