HOW TO ROOT ANDROID

                             

Google's Android operating system is riding a wave of popularity that has rapidly eclipsed Apple's iOS, and by the end of 2010 it's expected to overtake RIM's BlackBerry as America's leading smartphone platform. However, despite the relative openness and flexibility of the OS, your Android phone still isn't as powerful and customizable as it could be. To unlock all of your phone's potential, you'll need to root it.

WARNING: Rooting--adding superuser capabilities to your phone by altering its system permissions--is an advanced technique that the inexperienced or faint of heart should NEVER ATTEMPT. It's hacking, folks, and if done improperly it can destroy your phone. Do not follow any of the instructions in this guide or on any of the linked sites unless you are comfortable with the very real risk of turning your phone into an expensive brick. As of this writing, rooting is not supported by any carrier or manufacturer, and will most likely void your phone's warranty. In short: This stuff is for big kids only. No whining if things don't go your way.
