Navigon adding live traffic to iPhone navigation app, asks 'TomTom who?'

Practically all summer, the buzz surrounding TomTom's forthcoming iPhone GPS app was near deafening. But said noise apparently didn't penetrate the labs at Navigon, as that very outfit has produced what's easily the most full-featured option on the market today. Just a week after updating the already-great app with text-to-speech, iPod controls and location sharing, the company is now proclaiming that live traffic will splash down in October (at least in North America). The update will enable the software to utilize real-time speed data from drivers currently en route as well as historical information in order to alert you of slow-downs and re-route you when necessary. We've personally seen live traffic functions fail more often than not, but we're giving Navigon the benefit of the doubt here until we can test it ourselves. Best of all, it'll only cost MobileNavigator users (priced at $89.99) a one-time fee of $24.99 for lifetime traffic, and if you snag it within the first four weeks after it goes on sale, that rate drops to $19.99. So, TomTom -- what now?
