[Resolved]  Nokia N70 Music Edition Cell Phone — VIBRATING CONTINUOUSLY

Nokia N70 Music Edition phone was just 6 months old. I am using the vibrator "ON" for call alert. Howerver suddenly the vibrator mode did not stop even the incoming call is answered. Ultimately I need to switch the mobile and still vibrator mode was on and I felt the vibrator and sound. Then I removed the battery and re activated the mobile with the vibrator option "off". I fail to understand why this costly phone, within a matter of 6 months mal functions. Can any body suggest remedy or this need to be addressed to the service centre of NOKIA - India (Chennai South) only.
