Installing IPA file from iOS app

I am trying to install an IPA file from my iOS-app written in Xcode (jailbreak with root access). For now I am using installBash.sh from Installous folder. This script is supposed to do exactly what I want, but it doesn't work properly. The app is launching just fine, but there is no icon, and the app "Document" folder isn't registred properly (the installation process is just wrong). Does anyone here know how to install an IPA file from an iOS-app in the right way? I heard about installd or MobileInstallation but I have no idea how to us开发者_开发技巧e them.
