Apple Thoughts: TeleNav to Enhance 'Offline' GPS Capabilities in AT&T Navigator

"If there's two things the world needs, it's a complete lack of international roaming charges, and GPS signals that never fade."

TeleNav has announced that they will be supporting more functional "offline" use in their upcoming versions, including their iOS (AT&T Navigator) app. This means that the software will cache full maps and directions while online, allowing use while disconnected from a mobile connection, or when you're unable to get a GPS signal. One gotcha is that only the original map(s) and direction(s) are cached, so if you change your destination or route, you'll need to be online to make any updates. This capability will not cost anything additional, but will require (possibly significant) storage space for anything cached.
