Remove the two Phillips #00 screws from the dock-connector end of the iPhone.

Make sure to keep all the screws organized as you are taking the phone apart. They are different sizes.

Remove the metal handle from the suction cup. It's easier and safer to grip the suction cup's base instead of the metal handle.

Be very careful when opening the iPhone so that the cables under the display are not severed.

There is a rubber gasket between the silver front bezel and black display assembly. A bit of force is required in this step to separate the iPhone's display assembly.

Use a small suction cup near the Home button to gently pull up the lower portion of the iPhone's display assembly.

If the display assembly is too damaged to allow the suction cup to adhere, tape with a strong adhesive such as duct tape may be used.
