The Apple iPhone. Yes. The iPhone. Pretty much everything you need while traveling (with the help of apps of course). The iPhone is a currency converter, camera, flashlight, boarding pass generator, hotel finder, alarm clock, cheap gas finder, weatherperson, navigation system and of course you can make calls, send emails and text messages. I wouldn’t trade my iPhone for the world. Well, maybe a free trip around the world I could part ways with my supreme gadget.
