Joystick pressed in!

[dicicco2]

The black joystick button is permanently pressed in the down state. So everytime i touch something on my screen it things its the hold-and-click, not just the regular click.

As you can see this would be very frustrating. I'm over warranty and don't feel like spending $50 to get the same phone. Is there anything you think I could do to fix this. I'm pretty tech savy and I figure if the warrantly is already done I don't mind opening my phone.
