Apple's Self Service Repair program is now available in the US. If you have an iPhone 12, iPhone 13 or third-generation iPhone SE, you can buy key parts (such as batteries, cameras and displays) from a dedicated store and consult official repair manuals as you fix a device yourself. You can even spend $49 to rent a toolkit for a week if you'd rather not buy tools you're unlikely to use often. The program will expand to other countries later this year, starting with Europe.
