Want to alter the appearance of your iPhone 4 to make it stand out from the crowd? Cases are a good option but tend to add bulk and conceal the iPhone’s elegance. Adding a vinyl or leather sticker to the back is another alternative, but it feels cheesy at times and can cheapen the iPhone's overall look. How about replacing the fragile glass back entirely with something durable that still retains the iPhone's original aesthetics? Check out this metal panel mod for the iPhone 4, after the jump. I found this metal back on cnn.cn, an OEM cellphone parts company from Hong Kong. There are similar flat metal backs that can be found on eBay, but this is one of the few places that sells it with a beveled back. The slight bevel rounds out the back of the phone, making it feel less sharp. It also adds a tough industrial look.
For even more durability, adding a bumper and a front screen protector protects your phone further while still managing to keep the iPhone's refined look. The best part is, it's simple (only requires removing a couple screws; see ifixit's tutorial for installing an iPhone 4 rear panel) and cheap ($12.99 for the metal panel).
Remove two screws at the bottom of the phone with a Philips #00 screwdriver.
Slide back panel off by pushing the panel up with your thumbs.
3. Line up metal panel and slide down. Return screws.
