テキスト [title|iPhone 4 Repair] [summary]Fourth generation iPhone. Repair is straightforward, but the front glass and LCD must be replaced as a unit. GSM / 8, 16, or 32 GB capacity / Model A1332 / Black and White.[/summary] [summary_image|242904] [repairability|6] == Wallpapers == Check out our free [https://www.ifixit.com/News/14240/iphone-4-wallpapers-gyro-and-internals|iPhone 4 teardown wallpapers]! == Background and Identification == The iPhone 4 is the fourth iteration of Apple's cellphone line. Announced on June 7th, it is differentiated from earlier generations by having a squarish physical appearance, glass for both front and back panels, and a steel frame that doubles as reception antennas. Difficulty with repairing the iPhone 4 depends on which part of the phone fails. The front panel glass is fused to the LCD and digitizer, which means that the glass can no longer be repaired or replaced individually. Users who accidentally shatter the iPhone 4's front panel will have to replace all three (as a single unit) in order to successfully repair their iPhone 4. The back panel, however, is replaceable by unscrewing two screws and sliding up the panel. Replacing the battery, on the other hand, is easily accomplished -- even though Apple ascertains that no parts within the iPhone 4 are user-serviceable. To replace the battery, the user can follow iFixit's [guide|3141|battery replacement guide] to remove the back panel and disconnect the battery.
