I have not gotten the phone wet, nor have I dropped it. I have a Curve 8900 and in order to get the buttons to work, you need to hold down the return key (little backwards arrow key near the red power button) and press any other key.

Does anybody know what could cause this?

Still may be mositure. Can you return it? Do you have insurance?

returned it for a brand spanking new one!
