Unfortunately, the Galaxy S 4G cannot be disassembled further without prying the front panel off the inner metal frame.

Heat gun time!

Separating the front panel assembly from the rear panel assembly requires loosening the adhesive around the perimeter.

Add a little heat and some opposing forces, and BAM! Front panel and rear panel successfully separated.

On the back of the display assembly we find the Atmel mXT 224 touchscreen controller, which provides capacitive multi-touch capabilities, and is also found in yesterday's Motorola Atrix teardown.
