I forgot my lock gesture.

Hi -

To cut a long story short, I set a gesture lock and then forgot it. My phone is rooted and I can use adb, is there any way I can remove the gesture lock? I've already tried deleting the gesture.key file.

(Clarification: By gesture, I mean the one where you can draw an image. Not the 9-dot one.)

Thanks in advanced for any help, much appreciated.

Kris.
