AT&T announced on Tuesday that its new service, AT&T Global Navigation Edition, is now available on some of its handsets. The service will allow customers to maximize the GPS capabilities of their phone while traveling outside the country, truly putting the "global" in Global Positioning.

Used in conjunction with a data roaming package, the service uses data connections to download maps, preventing surprising high bills some customers have come home to after traveling abroad.

Surprisingly the service does not currently work with the Apple iPhone, however AT&T spokesperson Jeannie Hornung said the company is working with Apple to enable the service.

The Global Navigation Edition is one more strength AT&T can offer due to its GSM platform, something it's CDMA competitors will be hard pressed to equal.
