You will have to perform a factory reset of the device. Please note - Resetting will DELETE ALL DATA, including downloaded applications, and reset the phone back to the state before you turned on the phone for the first time.
Follow those steps to factory reset your phone:
1. Turn the power off.
2. Hold down the Volume Up, Power and Home (bottom center) buttons.
3. When the "Galaxy S GT-i9000" startup screen show, release all the buttons.
4. Use the Volume Up/Down button to navigate to "wipe data/factory reset"
5. Press the Home button to confirm.
