How To Repair Your iPhone At The Genius Bar Inside Your Local Apple Store

1. Visit Apple's website to make a Genius Bar appointment before you go into the store. Apple Stores are extremely busy, and if you don't have an appointment, you may have to wait for hours or end up being turned away. (Editor's note: I'm a former Apple tech and we're not exaggerating — please, do yourself a favor and make an appointment first!)
2. When you arrive, go to the Genius Bar to check in for your appointment.
3. Genius Bar appointments always include free diagnosis. If you're under warranty, many repairs can be done on the spot, but it all depends upon which parts are in stock. If you're not under warranty, the Genius will give you a quote for the cost of a repair.
