Unhappy accelerometer

just read a few accelerometer pages as my accelerometer is frozen and i cant unlock my phone now cos i have that sensor lock so i have to twist it 2 times anti clock wise to unlock it. when i open up teeter it is just stuck in the bottom left corner and can feel the vibrating as if it is hitting the wall on the corner 2x's a second. I have hard rebooted and no other software on there. Please tell me there is a fix or a bug because I dont think mine came with warrenty becasue I got as a promo. I am F without it. PLEASE PLEASE PLEASE gime some good news, or anything you know.....

Thanks heaps.
