I just got a new Blackberry Curve 8310, with built-in GPS. But just before giving up my old Blackberry 8700 I installed the new Google Maps with the "my location" feature. The "my location" feature is somewhat handy but the privacy geek in my has a few questions.
The feature uses signals from the cell phone network to approximate your location within a few hundred metres (depending on the density of cell towers in your area). When I installed it, I didn't have to give it any special permission to get access to carrier information or other stuff. Handy if I want it, but it makes me wonder whether any software installed on my Blackberry can get access to this data and perhaps transmit it in the background. That certainly raises privacy issues.
If anyone knows, please let me know.
In the meantime, here's a Google promotional video on the new Google Maps:
