GPS For The iPhone

Finally companies are making an effort to make GPS available on the iPhone. This is not a great option, but it is a start. The program is called Navizon, and it works without having any GPS receiver. I have not tried this program yet as I have taken the installer program of of my iPhone until the next major update so that they can get everything working good again, but there are already user responses to the program.

The program works by using cellular towers and wi-fi to triangulate the position of the iPhone. This is a great idea in theory, but it sounds like this is not very accurate unless you have lots of wi-fi signal all around you. Also, I don't believe that there is any real attempt to make a navigation system out of this program. The application can only tell you where you are, but it will not be able to give directions based on where you are. This is a disappointment for me, but it may be useful to some.

All in all this is a good step in the right direction and hopefully soon we will see a true GPS system for the iPhone with a GPS receiver and full program.
