Turn your iPhone 4S into a mirror - great for applying makeup, looking under your car, or signalling for help when trapped on a deserted island. This kit comes with a reflective plastic back and two basic screwdrivers (one pentalobe, one phillips - use whichever your phone has) to remove the back and replace it.
Replacing the back of an iPhone is a 5 minute project. Simply remove the two screws next to the dock connector, slide the old back off, and slide the new one on. Replace the two screws and you're done! This is one of the easiest mods you can do to your cellphone.
This product is for AT&T iPhone 4S's only! Adafruit also have one for model 4's as theyll as other iPhone tools and replaceable back options in Adafruit's iDevices category.
