iFunBox is a tool that helps you to manage content on your iPhone and other Apple devices in a way that is much easier that that used on iTunes.
Thus, the program will allow you to create backups of all your applications, and copy directly to your hard drive without having to jailbreak or do anything like that.
Besides this, with this application, you may use your IOS device as if it were a USB memory, introducing any file that you would have on a memory device.
iFunBox is an interesting alternative to iTunes. Although it can sometimes be somewhat unstable, it is certainly much lighter than Apple's official program.
