Exit the Market and press the "Z4root" application icon from your Android phone's application drawer. The Z4root homepage will appear.
Press the "Root" button on the Z4root homepage. The application will root your Android phone and automatically reboot it. When the Android phone turns back on, it will be rooted and you will have superuser permissions.
