Heat your iOpener and apply it to the bottom edge of the back glass for two minutes.

Alternatively, you can use a hair dryer or heat gun to heat the bottom edge of the back glass until it's hot to the touch.

Be careful not to heat the phone hotter than this—the battery is susceptible to heat damage.

Wait up to a minute for the adhesive to separate and a gap to form between the back glass and the frame.

If a gap doesn't appear after one minute, apply more heat and rotate the handle a quarter turn. Let the Anti-Clamp do the work for you, repeating this process as necessary.
