Some iPhone 4(S)s have a new style screw on the bottom called a Pentalobe. Its similar to a Phillips but it has 5 points instead of 4 like the phillips. This requires a special tool to remove or install it. If you need it, we can provide this tool! :)

Each screen is tested thorougly before shipping. We will not be liable for any damages that may result from unprofessional installation of the parts. We advise buyers to exercise extreme care when installing the replacement screens as components are delicate.
