Looking for specifically what commands/process the iphone does when you select
Clear History, Clear Cookies, and Clear Cache.

I'm interested in using a shell script to automate the deletion of the files or follow the same procedure the iphoneOS does when you select these actions rather than have to constantly press through the menus each time.

If you know what commands or actions (I presume deleting specific files) it follows, please reply back and let's see if we can automate it.
