Good News for iPhone Addicts team behind Installer.app released Desktop Installer. With Desktop Installer you can download and install App available in both Cydia and Installer and the action is controlled through your PC. According to RipDev InstallerApp is a native Mac OS X application (soon — for Windows too) that allows you easily download applications from Installer and Cydia directly onto your computer, and install them to the iPhone connected with USB cable. Now you don’t have to make a choice between alternative installers, you can get the best of both worlds, Installer and Cydia — InstallerApp supports both! Just add a your favorite repository in the Preferences window and application will automatically recognize its type and will show the packages from that repository, so you’ll be able to download packages to your computer and install them to a USB-connnected iPhone. Desktop Installer is not a freeware it costs 7$ and i think they really deserve it go ahead n grab your copy now it’s really a time saving application.
Fast Packages Restore : If you ever had to wait on a new iPhone firmware update because you didn’t want to re-install all those “not from the App Store” apps, InstallerApp is exactly what you need. Synchronize all applications between your iPhone and computer, install the new firmware and synchronize all the apps again back to the phone — no more painful downloads and installation directly on the iPhone.
Save the Traffic : If for some reason you don’t have an access to the WiFi network to “let iPhone out” onto the Internet, you won’t have to download applications over EDGE or 3G networks wasting often expensive traffic. Download all the required packages straight onto your computer that is connected to the Internet (whether it’s an Ethernet cable or even a dial-up connection), and then simply synchronize all the downloaded packages to your iPhone over the standard USB cable.
Built-in Pusher : InstallerApp comes with free built-in Pusher — software that can install Installer.app on your iPhone without “jailbreaking” it, so you can use App Store and Installer simultaneously without putting your private data at risk. By default Pusher will not install a set of command-line utilities and unlock the system partition as it’s usually is done by some popular jailbreak solutions and may lead to additional instability of the iPhone software, but it will do so if that is what you want.
Requirement : InstallerApp requires Mac with Intel processor and Mac OS X 10.5 Leopard operating system or higher. InstallerApp supports first generation iPhone and iPhone 3G — as of this moment iPod touch is not supported. iPhone firmware 3.0 will be supported shortly after jailbreak for it is released.
