Will an Apple Store refuse service for a jailbroken iPhone?

I have an iPhone 6 with a cracked screen. I have scheduled a Genius Bar appointment to have my phone repaired, however my phone is jailbroken. I know it voids warranty and I don't have warranty to begin with, I'm paying for the repair completely. Since the screen is a hardware thing and wouldn't matter if I was jailbroken or not, I was just curious because I don't want to have wasted my time for them to refuse service to me.

IPhone 5s making screeching/static noise from speakers?

Yesterday I heard a screaming sound coming from my phone but I had no apps/music pulled up that could explain the noise. Not even 5 minutes ago, I went to watch a video and had a very loud static noise coming from my speaker. I turned my phone off with the lock and home button and it fixed it. What was it? What do I need to do?
