There is a notch on the underside of the display just above the headphone jack that is the safest place to begin prying the phone open.
Pull up on the suction cup to slightly separate the front panel assembly from the rear case.
Take your time and apply firm, constant force. The display assembly is a much tighter fit than most devices and is held down with adhesive.
Once a small gap has been opened, insert the flat end of a spudger above the headphone jack.

Twist the spudger to open the gap more and break it free from the adhesive.
Keep pulling up on the suction cup while twisting the spudger.
