I'm taking my iPhone 5C to the Apple Store tomorrow because my headphone jack hasn't worked since the first month I got the phone. I talked to a Apple Rep and he told me that fixing the jack would be covered under the warranty as long as there was no "accidental damage". The only thing is that my phone also has a crack on the front of the screen. I'm not sure if that would hinder the store from fixing my phone under warranty. The crack and the headphone jack have no correlation because I cracked my phone months after the jack stopped working. Do you think they will fix/replace it under the warranty with the crack there? Once again, it's the jack I want fixing, the screen has nothing to do with it. I just know Apple can be tricky about they're warranty and was thinking that they might take the crack on screen as "accidental damage".
