TomTom's New iPhone GPS app

TomTom is a big GPS company as you know, near days, TomTom has made a GPS app for iphone.
Sure, iPhone 3G is going to offer some solid GPS functionality right out of the box. Apple's updated iPhone site shows off some of the new features—most notably turn-by-turn directions—but TomTom is officially coming to the rescue of users who need a little more from their GPS.

Reuters reports that Dutch-based TomTom is just about ready with an iPhone version of its software that it plans to sell through the iTunes App Store. A price hasn't been set yet, and the company was remarkably low on details, but one can imagine that TomTom can bring some GPS functionality to the table that goes beyond the iPhone 3G's default abilities.

One of the most likely advantages of TomTom's software could be a local database of maps that users can access and customize even if they don't have an internet connection (3G/EDGE, Wi-Fi, or otherwise). TomTom can also bring its own custom array of features and services, including real-time traffic reports (that go beyond the ambiguous red/yellow/green color overlays in Google Maps) and instant messaging for a lifeline while traveling. TomTom's software for other GPS devices can also do things like warn you if you're speeding; perhaps the iPhone could too.

TomTom wasn't specific about when its iPhone client will be ready, but it will be sold for an as-yet undetermined price.

iPhone getting open-source GPS module

It was quite a shame last week when we uncovered a leaked photo of an alleged iPhone GPS module from TomTom, only to discover that the whole thing was a well-executed prank. Well, all hope is not lost, mapping enthusiasts: a company called Part Foundry claims to have an open-source GPS module for the iPhone in the works and they hope to sell it for a reasonable $89 in February. Before you whip out your wallet, however, there are a few catches. First off, this device is not officially supported by Apple and as such, you'll have to Jailbreak (i.e. hack) your iPhone to get it to work. Second, it only does one thing: figure out your current GPS coordinates and plug them into Google Maps. While the lack of a navigation app will probably be a deal-breaker for most GPS enthusiasts, the fact that the module is open-source means that it's quite possible that some kind soul out there will decide to write one once the product is released. Still, that's not a sure thing, which certainly makes that $89 price tag a little harder to swallow.

IPhone GPS?

The absence of GPS is one of the main criticisms against the iPhone, as did the lack of 3G. If the latter would certainly appear that in the models of next year, there are now almost filling an application with the absence of GPS.
Géolocation triangulation GSM

The application Navizon, available for the moment only in English, in fact uses the GSM standard relays and not a satellite positioning like a GPS. In this way, and taking the position of three relays, Navizon can show how cell to another. According to our brothers Blog iPhone, the application is already completely usable in France on the phone from Apple.
Although less accurate than GPS

If the system is clever, it is still far less precise than GPS. The accuracy depends on the density of the cellular network to where they are. In urban areas can be thus approaching the hundred meters, while in the middle of a campaign we will be satisfied with an accuracy of between 500 meters and several kilometers. The application Navizon is available now at a price of $ 24.99.
