Use a heat gun or an iOpener as a heating tool. This guide explains how to use the iOpener.
Evenly apply heat to the edges of the touchscreen to loosen the adhesive. Continue to Step 3 once the edge of the screen is warm to the touch.
Do not let the iOpener/heat gun remain on one spot for too long. Excess heat can damage the phone.
When reassembling the phone, use the iOpener/heat gun to help the adhesive fuse to the new screen. Heat the screen edges, apply pressure to the screen, and hold the screen in place until it is secure.

Avoid damaging the LCD screen connector while prying along the screen edges. It is located on the left edge of the phone, across from the volume controls.
