Introduction: DIY Iphone 4 Case
Okay, this is not exactly A CASE, but for what is worth, it will shield the stainless steel band from the hyped up antenna issue and protect it from getting scratched.
For the back, I leave the clear plastic sheet that ships with the phone (actually I doubled up and apply the front plastic sheet on top of the back one) and cut the tab so it wont stick out.
You can use a three hole punch to punch out two holes for the camera and the flash.
Step 1: You Will Need
Step 2: Electrical Tape
Cut a piece of electrical tape to 40 cm x 1 cm
Cut a 4.5 cm x 0.3 cm hole somewhere. This will be the opening for the bottom speaker, mic, and ipod connector. The location depends on where you want to seam ends up. I decided to have the seam on the simslot side so I cut this slot about 6 cm from one end of the tape.
Step 3: Simply Align the Slot With the Bottom Speaker, Mic, and Ipod Connection
It may take a couple trials. Be patient. Electrical tape is very forgiving for retaping. Apply some mild tension for best result.
Step 4: What About the Other "holes" Needed to Cut
When you get to the volume controls, reduce the tension you apply onto the tape.
Briefly cover the mute button, use the utility knife to lightly nick the margins of the mute button. Then put that portion of the tape on your cutting mat (or desk) and cut a small rectangular hole. Resume wrapping.
Repeat for the other holes. I dont use the headphone jack so I just cover it. But you do need to open a small hole for the top noise-canceling mic though.
When you come to the on/off button, again reduce tension.
Leave 1 cm overlap with the tape ends.
Step 5: That's It!
Should take you no more than 30 minutes
