Once the area of the front panel to the right of the home button has been heated adequately, it should be easy to insert a plastic opening tool between the outer plastic bezel and the front panel right next to the home button.

Use your plastic opening tool to gently create a small gap between the front panel and the outer bezel to the right of the home button.

If the adhesive is difficult to separate, don't be afraid to heat it up again. Excessively prying and bending the front panel when the adhesive is not pliable enough can easily cause it to crack.

Insert a guitar pick into the small gap created by the plastic opening tool.
