At long last, iPhone users who have grown increasingly frustrated by using Google Maps as their primary navigational tool can find relief... sort of. Available right now in the App Store, XRoad's G-Map application requires no internet connection whatsoever in order to function; rather, it packs oodles of maps into a 932MB package that covers most of western America and a few sporadic locales on the east. We're a bit baffled (and angered) by the not-at-all-comprehensive coverage, but we suppose we can expect updates to patch the gaps in the near future. It provides most of the same amenities you're used to seeing on real-deal GPS units, including POI editing, memo capabilities, location searching, etc. A word of caution, though: early reviews don't seem too stoked about it, so you may want to gloss it over good before hitting your card for $19.99.
