Nowadays our cell phones have become an essential part of our lives; we are reluctant to go anywhere without this essential device. Everyday new functions are dreamed up and developed to make our lives easier and more enjoyable. Did you know that smart phones can even be used as a tracking device? This handy feature means that we can get all the information about our friends and relatives while we are apart. We can actually acquire this information without informing the other person or persons. Also, our mobile phone allows us to actually locate another person since their location appears on the screen when we call their number. For example, the BlackBerry has a mobile tracking device that determines the current location of your cell phone as well as the person you are trying to contact, which is especially useful in the case of emergency such as when you are lost or in a new area.
There are many useful apps that you can download to take advantage of this amazing technology. You can use the smart phone's on-board GPS to see maps to pin point your location, as well as let you know who else might be around to meet up with. Then you can check an app that will tell you all that is happening at that moment where ever you are like the closest restaurants and movie theaters or maybe live shows and specials. If there is an emergency the authorities can instantly locate your smart phone's position and send help. You can also use the GPS to give you street by street driving instructions to find your way and prevent you from ever get lost again.
