Try doing a wipe data/factory reset from the recovery menu. To get into recovery, power phone off and wait until phone vibrates. Press and hold the following keys, Volume up + Home + power, when phone boots to the boot screen(Samsung Galaxy S GT I9000) release just the power key. From there use the Vol Up Down to navigate to wipe data/factory reset, use the power key(some phones it's the home key) to ok your selection.
