Power and Lock Button Stuck, Requires Heavy Pressure
This is a first-run iPhone 4 that's in otherwise perfect condition.
Last night, the power and lock button became extremely difficult to push. I assume that there is some debris or that the button itself no longer presses (an issue I've noticed with Mid-2009/2010 MacBook trackpads as well).
I do not know whether or not there is a physical button that is being pressed, part IF182-004-1 shows a button with a level that I assume is actually pressing a real button.
I have removed the back of my iPhone, but I'd like some more information before I remove the logic board and void the warranty. The replacement guides don't have any information about this button.
