Chalk up another two wins for cheap consumer GPS. Like Google Maps Navigation before it, the MapQuest 4 Mobile iPhone app has just now added gratis turn-by-turn voice directions... and ahead of schedule, TomTom has begun bundling its new 2010 Personal Navigation Devices, including the XL 340S and the XXL 540S -- with lifetime traffic and maps subscriptions. The latter are now available on Amazon for a $30-per-lifetime-subscription premium in a variety of increasingly feature-filled flavors, with helpful T (traffic), M (maps) and TM (traffic and maps) suffixes so you know which TomTom is which. If you prefer buying from brick and mortar, TomTom expects retail availability beginning in April. Full list of supported TomTom models and expected MSRP after the break.

Update: The 1.5.0 iPhone update to MobileNavigator from Navigon that includes MyRoutes, Facebook and Twitter integration, and Panorama View 3D is finally up on iTunes as well.
