There are a variety of gadgets out there for travelers…but there is one gadget on the horizon that could end up being the ultimate travel gadget….the iPhone.

Why?

Well, for starters the new iPhone 3G (set to launch on July 11th) will have built-in GPS navigation. It’s certainly not the first mobile phone to feature that option, but that’s not what makes the iPhone so unique.

What makes the iPhone different from every other phone on the market right now is what is “under the hood” of the device. See, deep inside an iPhone is a robust operating system…Mac OSX. This is the same operating system as Apple’s Mac computers, which are gaining more and more popularity every day.

This system gives the phone an amazingly powerful platform for software developers to begin creating applications…and they are…by the thousands. Many travel and entertainment applications are in development.

You’ll be able to keep track of your golf score from you iPhone, or use Tom Tom GPS on a device that is probably smaller than your TV remote. You’ll be able to surf the Internet and find directions and points of interest like never before on the iPhone, and with the amazing development community out there the options for travel specific applications are virtually unlimited.
