As Android phones get more popular people get interested in pushing their phones to the limit. Like Apple's iOS devices you may in a form "jailbreak" to gain full access. In Android it is not called Jailbreak . The word "root" is used. This allows you to back up your Android phone, put custom ROM's and basically fully customize it. Unrevoked allows you to download some software that will "root" your phone in one click. I have done this with my Android Droid Incredible. It was a simple step to gain access to the root structure and modified its contents. Below are the cellphones that are supported by Unrevoked. Have fun and enjoy but I am not responsible for any damage to your phone.
