The glass front panel on the second generation Touch has a plastic frame glued both to its outer edge and also under the wide black strips at the top and bottom of the device. The frame also has a rubber strip that surrounds the edge of the glass panel.

The picture at left (front panel already removed) shows the locations of the metal clips (shown in red) that snap on to the plastic frame. In the next few steps, try to pry the front panel up from the gaps between these clips.

Also, be mindful of the very thin and delicate touch screen ribbon cable (connector location shown in orange) attaching the front panel to the upper left corner of the Touch.
