What is Rooting?




Getting root or rooting your phone is the process of modifying the operating system that shipped with your device to grant you complete control over it.


This means you can overcome limitations that the carriers and manufacturers put on your phone, extend system functionality, and even upgrade it to a custom flavor of Android.


The name root comes from the Linux operating system world, where the most privileged user on the system (otherwise known as Administrator on Windows) is called root.


Quote:
rooting does *not* mean installing a custom ROM (a ROM is a modified, "aftermarket" OS).
Installing a ROM may require rooting first, but just rooting can be usually done in only a few minutes, keeping your stock OS otherwise completely intact.



Usually rooting is fairly simple - in most cases you can find several videos and articles on the web that explain how to do it on your specific phone model - just Google "YOURPHONEMODEL root".


Rooting is not something manufacturers or carriers approve of but they can't really prevent it from happening because the rooting process usually exploits a vulnerability in the operating system code or device drivers and allows the "hacker" to upload a special program called su to the phone. This program is the one that provides root access to programs that request it.


Quote:
Contrary to popular belief, su stands for "switch user" and not "superuser."
Another program called Superuser Permissions is usually bundled with all root methods. It gives you a chance to approve or deny requests from any application that wants to utilize root. Superuser Permissions essentially replaces the conventional root password with a simple Approve/Deny prompt, which isn't as secure as having a password, but is far more convenient on a mobile device.

I think its too risky to jailbreak your iPhone by yourself but for someone has experience hacking their PSP CFW, this will be easy.
