I've had my Thunderbolt since last March and haven't had any issues with it until this last week or so. It appears that the power button does not work any more when I try to lock my phone. When I push it, the screen goes black and immediately turns back on. This is causing my battery to drain ever more rapidly than before. I've tried to un-jam the button, but no luck.

What are my options for this, as this is making my phone absolutely unusable if the battery is constantly draining.
