Today I decided to take a chance and try another one of the free GPS programs that now support BlackBerry Devices. As a fair warning most of these free applications are on the bleeding edge and do not even come close to Google Maps or Telenav in terms of ease of use or even getting it to work. I am only providing this information as a heads up and not as a how to description of how to get it to work. To be honest it does not work half of the time but it is a step closer to true GPS on BlackBerry devices.
The application I tried was called MGmaps that promises to deliver on device maps for BlackBerry devices. This is actually quite promising since they already support on device maps for other phones. This is important since all of the current GPS or mapping solutions require a constant data connection. MGmaps has the ability to show overlays like the OnNYTurf and TubeJP projects that overlay subway maps on Google Maps which is pretty cool. Keep in mind this program is quite buggy and fickle so I had to really play with it to even get it to work at all. The software is actually a combination of MGmaps and Navizon which is an application that allows even non GPS devices to triangulate their location (or something like that). You can download the application OTA or for Desktop installs at this link. This program is actually quite promising since it has offshoots such as gmap-track.com that allow you to plot and track your location on a map.
If you still feel like checking it out let us know what you think. I am sure the developers at MGmaps would love some extra beta testers. I also feel that if we let them know how much we want on device GPS maps they may have more incentive to support it.
