There are no real surprises in the teardown. The micro SIM card (as opposed to a mini SIM card) is still slightly novel, but hardly unique. Samsung phones are pretty slim, but hardly impossible to crack as smartphones go; the DROID RAZR, with its armored construction and teeny tiny seams, is a lot harder. A couple of non-standard screwdrivers is all it takes to separate pretty much every bit of plastic, metal and circuit board.
