InstallerApp is a native Mac OS X app which will also be available for Windows soon as well, and enables the user to download apps from Cydia and Installer direct to their computer and then install them on the Apple iPhone via a USB cable.

InstallerApp will sync all apps between the iPhoner’s Apple iPhone and their computer, install a new firmware and then re-sync all the apps back to your iPhone thus avoiding the necessity to download direct to the iPhone.

InstallerApp for the Apple iPhone includes free Pusher software which can install InstallerApp onto an Apple iPhone without the need of jailbreaking, although Pusher will not install command line utilities to unlock the iPhone unless required.

Furthermore, some Cydia apps require dpkg to function and Pusher can accomplish this without messing up the iPhone file system and will not replace any libraries like Cydia.

InstallerApp is available for download via RipDev and costs US$7.00 for the licence which allows the synchronisation of up to 3 Apple iPhones.
