So I-Phones clearly have a ton of different features. You can send email, manage your contacts, update Facebook, take pictures, surf the web, check the weather and the list goes on.
But have you ever used your I-Phone as a flashlight? The background light can be particularly handy when you are walking down a dark alley, in an garage or getting up in the middle of the night to use the bathroom. My favorite use is when I get up at 6am to head to the gym. It is still dark so I use it as a flashlight to get dressed, find my gym bag, brush my teeth and so on. This way I don't have to disturb anyone by turning on the light (which is everyone else who is sleeping comfortably in their warm bed while I get my a** kicked at boot camp).
I suppose I am also saving energy too by not turning on the light - an added benefit!
Now if I can only get AT&T to fix the cell coverage so my actual phone worked somewhere beyond just my closet...
