The Genius Bars in Apple's retail stores are supposed to be convenient ways to answer questions and get repairs, but the ever-growing deluge of customers sometimes makes it a pain.
Both uSwitch and leaker Sonny Dickson understand that Apple is working on a support app for iOS that would help you get the fix you need.
The app would narrow down the cause of your problem by asking questions, and offer chances to contact support, book a Genius Bar appointment or fix it yourself through how-to guides.
Even if you tend to breeze through support yourself, it might save you from waiting ages for others to walk through basic problem-solving steps.
