I've created a directly deployable .deb installer file of my iPhone 3GS and 4 Video Camera Enhancer tweaks for iOS5+ (see THIS and THIS, respectively, for an explanation, quick tutorial and sources). They allow for installing the tweaks without having to have access to a desktop Xcode. I've also made sure the installers themselves set the right write permissions of the configuration file (and its enclosing directory) they modify upon tweaking the video recording parameters. This means installing them has become orders of magnitude easier.
