We’ve had the iPhone 4 in our hands for only a couple of days, which happens to be just enough time to create a comprehensive set of repair guides! We hope you never have to use our guides, but we’ve got you covered if you do.
During our teardown, we investigated the repairability of the front and back glass panels. It turns out that you’ll be able to replace the back glass with little effort, but you won’t be able to replace the front panel without also replacing the LCD. The LCD, glass panel, and digitizer come as one unit in the iPhone 4, and they are inseparable without damaging the device. We’re going to keep investigating to see if there are some methods of separating the LCD from the rest of the front panel, but the “outlook [is] not so good,” so to speak.
The good news is that whatever goes wrong with your beautiful iPhone 4—whether you crush the home button, damage the front-facing or rear-facing camera, or short out the iPhone logic board while taking a swim — you can fix it, and we can help.
