The iPhone 3G will be my new travel companion when I leave for Zurich, Switzerland tomorrow morning (yep, I finally bought one)!

The iPhone has a lot to offer the international traveler, and here are 10 ways you can use the iPhone to help you on your next trip abroad (most are applicable even if you're just traveling to another state or province).

  1. Mind the Time with a World Clock:

    Keeping track of the current time is the first thing I worry about when I travel across multiple time zones, and the iPhone lets you add a clock for every imaginable city in the world. I've added a clock for my destination city, my lay-over city, and my home city.

  2. Pack for the Right Weather:

    You can add Yahoo! weather reports for any city, just by opening the Weather app and clicking the little "i" at the bottom right of the weather screen. You can store multiple weather reports and easily flip through them to see what the weather is like in other areas of the world.

    Looks like it's cold in Zurich in October, so I'll be sure to pack warm clothes for my trip.

  3. Manage your Monday with Currency Convertors:
