[Request] ICS Camera power button mod (screen lock)

HI,

Can somebody make this mod:

in gingerbread camera when you press the power button, the touch screen and buttons stop working and the camera is locked recording and there is no way you can accidentily hit the Stop button.

in ICS this is not there and i often press the stop button by accident: I film myself with my hands on the touch screen.

Is there somebody who can make this mod or point me in the right direction making this APK.

thank you,

Jerry
