Support your iPhone on something sturdy such as a hardcover book so it rests hands-free and parallel to the ground; this makes it easier to work with in the following steps.

Use a hair dryer to heat along the bottom edge of the iPhone. The glass should feel slightly too hot to touch.

For complete instructions on how to use a hair dryer, check out this guide.

Wait one minute to give the adhesive a chance to release and present an opening gap.

Insert an opening pick under the rear glass when the Anti-Clamp creates a large enough gap.

If the Anti-Clamp doesn't create a sufficient gap, apply more heat to the area and rotate the handle a quarter turn.

Don't crank more than a quarter turn at a time, and wait one minute between turns. Let the Anti-Clamp and time do the work for you.

Skip the next two steps.
