I’ve had the BlackBerry Bold for a while now and I knew it had a GPS, but was wondering if there were actually any useful applications for the technology. Well, since this week I have days off, and Nhut is working, it gave me a chance to try out a few applications that use the GPS. So, first things first, in the Phone Options, you want to make sure that the GPS device is enabled. You can see from the screenshot below the options I have enabled on my BlackBerry Bold.

The first new application I installed was Where 2.1 from where.com which uses the GPS for updating location based information, for sites like Accuweather, GPS twitter and Gas Buddy. It seems pretty useful, but I’ve had some trouble getting it to pick up GPS information, or the phone wasn’t acquiring the GPS satellites well.

I hadn’t noticed the difference in Google Maps between the BlackBerry Pearl and the Bold, but it also uses the device GPS and is a lot more accurate in showing location than triangulating off of cell towers. The accuracy measure drops from “within 1000 meters” to “within 3 meters”. In the screen capture below, the location pointer accurately shows where I am inside the house.

The one option that wasn’t enabled by default, that seems interesting is geotagging photos taken with the Bold’s built in camera. You can see in the camera options screen that the option is enabled.

The geographic information from the GPS is stored in the JPEG’s EXIF data and can be used by sites like Flickr to map where your photto was taken. Check out this photo on Flickr, in the right hand column, under additional information, it shows the location where the picture was taken, and includes a link to a map of the area.
You can see the full EXIF data in the Photo properties in my gallery.
Yellowpages.com has a downloadable app for the Bold which also uses the GPS for location based searches. Like Where 2.1, I’ve had trouble with it’s ability to pick up GPS location from the device, but when it does pick up the data, it’s pretty good at finding local businesses.
