Probably a stupid question but what does the flashing blue light on top left of the 'phone (under the N80 sign) indicate. Its not mentioned in the instructions and seems to flash at random. Have checked bluetooth is off, 3G connection available and not, etc but to avail.
The flashing blue light means that "sleep mode" is turned on. Twenty minutes after the screen saver has been activated, the display is switched off to conserve battery life. The blinking LED indicates that the phone is on.
