I jailbroke my iphone 5s and now its broken?

A few weeks ago I jailbroke my iphone 5s. I really enjoyed the perks that came with this, but now my phone has water damage and the screen is unresponsive, but it can still turn on and display the lock screen I just can't get into the actually phone because I can't slide or type in my passcode. I have a warranty with Roger, but they will be bale to see I did this to my phone simply by looking at the home screen. I can restore my phone because the phone must be unlocked to do this, which is something i can't do. What should I do now? Fill my phone with the water to the point it won't work anymore? Or what are my options here I'd appreciate any advice given.

This will mean you don't need to unlock your device in order to do a restore via iTunes
