Samsung Galaxy S II (Sprint Epic 4G Touch): Complete teardown

The Samsung Galaxy S II (Sprint Epic 4G Touch) was relatively easy to disassemble. It uses standard Phillips screws and the internal components are easily accessible. Unfortunately, the display and front panel (digitizer) are fused together, making replacing one or the other difficult.
