The iPhone is a great travel aid all by itself, but some downloads from the App Store make it even better. The Facebook app for the iPhone is a quick and easy way to keep up with friends and family when you’re traveling. It lets me send updates about where we are, what we’re doing, and even share the cool pictures that I snapped along the way. I took a few the other day at the Nebraska Wildlife Safari. That evening, I used Facebook to share them. It’s like sending a postcard to multiple people—without the stamp.
