If you are very keen about travelling and doing the navigation by yourself, it is very good to have the Nokia 5800 Navigation Smartphone on hand. The excellent features that it has completely overwhelm me whenever I try to open it. These features include a program to recognize penmanship, accelerometer for easy rotation of screen, and a proximity detector that will automatically shut off the phone in very tight situations. There are three means of transmitting data which include Bluetooth, GPRS, and Wi-Fi. This phone is really the unit for the individual who wants power in his or her hands. How about you? What can you say about this very cool phone?
