Oh SAS, what a pain! Sallyanne, did you happen to buy insurance on your phone? We all have insurance on ours ($3 or so/month), but they will replace the phone, no questions asked, if you do. Scott ran over his with the car one time. Darn thing would still ring, too, but it had no screen and the buttons were mashed. That insurance came in good that time. And I have had several replaced because they weren't working properly.
Good luck!
