What exactly is Xbox modding? Modding is the practice of bypassing built-in security measures and restrictions which are programmed into a system by the original manufacturer. By modding the Xbox 360 a gamer can do things that Microsoft never imagined (or intended).
If you do decide to mod your Xbox 360 you should be aware that this will completely void your warranty. You will also lose the ability to use Xbox Live as well as the Xbox Live Marketplace. These are some of the things you must consider before you decide to go forward with modding your Xbox or Xbox 360.
