According to 9to5Mac, Apple plans to offer an upgraded iPhone trade-in program for iPhones with damaged screens, cameras, or buttons, and a program that allows Apple Retail Stores to install screen protectors on iPhones.
Currently, the Apple Store Reuse and Recycle iPhone trade-in program lets you bring in an older iPhone and trade it in for credit toward the purchase of a new model. However, iPhones with cracked displays, or broken cameras and buttons need not apply. That may be about to change.
9to5Mac says that, starting this week, the updated program will allow Apple Stores to give credit for iPhone 5s and iPhone 6/6 Plus units with damaged displays, cameras, and buttons within reason. Apple believes that this new program will encourage new iPhone upgrades versus a standard iPhone screen repair, the article says. 9to5Mac also says that Apple is teaming up with Belkin to allow in-store installation of screen protectors on its iPhone (and, presumably, iPads, as well).
