Use the flat end of a spudger (or an opening tool) to pry the touch screen cable connector up off the upper logic board.

Now that the front panel is out, check it for damage. If the plastic surround is not flush with the front face of the glass panel, gently peel it off and stick it down.

Be careful not to scratch the front panel on the underside of the black portions, as the scratches will be visible once the device is reassembled.

Be sure to clean both the face of the display and the inner surface of the front panel, as any dust or fingerprints will be trapped inside the Touch once it is fully reassembled.
