Sanyo has announced the new  Sanyo A5520SA mobile phone designed for KDDI telecom in Japan. The unique feature on the A5520SA is the inclusion of a loud buzzer in times of emergency. You turn on the buzzer by pressing a button for a long time. This will alert nearby people and neighbors in case you need help for any particular reason.  Of course if no one is around you at all this may not work but it’s better than nothing. You also get a 2.2 inch 262k color screen, a 1.3 megapixel digital camera, speech to text for Japanese speech, a weight of 105 grams, and 18 MB of internal memory.
