BB Storm 9500 :: Phone Dialing And Speed Dial Trouble?

Today the dialing features on my relatively new (summer 2009) Storm started going strange. When in the phone dialing screen, if I press and hold a number key with an associated speed dial number, the phone would dial another number elsewhere on the speed dial list (e.g. press and hold "3" made the phone speed dial the phone number assigned to "5"). After removing and replacing the battery and rebooting, the trouble didn't clear.In fact, things got stranger. The phone would not dial voicemail when the "1" key was held down (even though the speed dial list still listed the correct number, etc.) When I cleared and tried to refill my speed dial list, no number keys on the keypad would make the speed dial spring into action. But, pressing and holding the "3" key did make the phone ask if I wished to assign a speed dial to the number "5" as though that were the key I'd been pressing.Suggestions?
