Looks like the iPhone 3.0 firmware plus the new 3Gs hardware will give the dedicated GPS market a run for it’s money. The new hardware includes a magnetometer, otherwise known as a digital compass. Combine that with the A-GPS, which supplements the slow satellite signal with fast WiFi and cell phone tower triangulation, and accurate and timely turn-by-turn navigation is possible. Both TomTomNavigon, , and TeleNav have jumped into the fray, joining X-Roads which was briefly available in a crippled form on the App store. Garmin might be shooting itself in the foot by staying out, but they have their own GPS + phone plans already. Besides the added precision of the new hardware, it’ll be easier for developers to incorporate maps directly into their apps. We should see a whole new class of apps available. Imagine walking along a street and pointing your phone at a building, statue, mountain, road, etc and have reams of helpful information come up about that particular feature. A great wayfinding device in the making!

[Editor's note: Not for the faint of hear, but great proof of concept of what the iPhone is capable of.]

Six months after the App Store was launched, the iPhone app gray market lives on: turn-by-turn navigation has come to jailbroken iPhones in the form of xGPS. UPDATED

xGPS uses Google’s map data and driving directions, adding a real-time navigation readout and a voice engine. You can also select a map area to download ahead of time, just in case you expect to lose your data connection during the drive. As you can see in ModMyi‘s video above, the app also supports a number of external GPS units, so 1st-gen iPhone and iPod Touch users can get in on the monotone fun too.

The project has been gestating for a few months now, but many vital features, including the voice engine, weren’t implemented until this release. xGPS 1.2 is now will soon be available in Cydia. UPDATE: An older version without vocalization in current available in the repositories, but the newest version is expected to be publicly available within the week. [xGPS via ModMyiThanks, Aleksey!]
