Programmatically installing the application in iPhone

I like to install the .app programmatically from my application. I hope it can be done only through jailbrokken iPhones. Can anyone 开发者_运维技巧share some knowledge regarding this. I found a application called "CallMe" in cydia store. This application programmatically installs the other one. Or how to install the iPhone applications (.app) file in the iPhone from the terminal. If we programmatically execute those system commands, I hope it's possible to install the application programmatically in jailbroken iPhones.

As far as I know, you only need to download (somehow) and put the unpacked application in /var/mobile/Applications on the phone. Look at the existing structure (with a terminal, on a jailbroken phone) and follow it.
