Can someone tell me what component this is?

I'm pretty sure this component has something to do with the power switch and I think it's a resistor. This is a liquid damaged device that belongs to a friend. He drank a little bit too much the night before, passed out, and ended up wetting the bed with his phone in his pocket. After running it through the ultrasonic cleaner, baking, reflowing the board, reworking components that seemed like needed reworking and replacing the battery, I got everything working EXCEPT for the power button; I tried three different power/volume switch flex circuits.. still nothing; the iPhone would only turn on when I plugged it into a charger. After inspecting the board again through my scope, I noticed that this component, along with the trace that goes up the board to the next component, was corroded. So I cleaned it up, reworked it, ran solder up the trace and.. to my surprise, the power button switch WORKED! But I decided to touch it up a little bit more with my iron and ended up flinging the component to... who knows where, and the power button switch is once again.. no longer functional. Want to know the details of this component to see if I can order it from digikey or.. wherever.
