If there's two things the world needs, it's a complete lack of international roaming charges, and GPS signals that never fade. Oh, and for Slash to not play the last Super Bowl with the Black Eyed Peas -- we suppose that makes three. At any rate, at least we're moving somewhat closer to a reality that solves the middle issue, with TeleNav announcing this week that it'll be implementing "hybrid navigation technology" into its apps (including the new iOS version) in the very near future. Post-implementation, TeleNav software will automatically cache maps and directions for routes you look up, and if you drop your mobile connection or GPS signal en route, you'll still be able to have a look at the original plan. 'Course, any deviations from the prescribed route will lead to endless frustration, but if you (or your 63 year old father) are familiar with following a paper map, you ought to be just fine. The company asserts that the new addition will be rolling out to "select applications" that it develops for carrier partners "in the near future," and you won't be ask to pay a dime more for the added convenience. Sometimes life's just too kind, eh?

Update: TeleNav pinged us to say that its version will actually download full maps to the device (so you'll need a good chunk of free space), so you really won't suffer too much from not having a live connection. Also, the iPhone build is better known as AT&T Navigator v1.8i.
