On the BlackBerry Bold, there is a setting labelled "
GPS Extended Ephemeris" within the Options, and points to a configurable ephemeris server.
The word "Extended" suggests to me, that BlackBerry Bold is capable of both native GPS and assisted GPS. Basically faster accurate locks whenever there's 3G reception at the same time as GPS reception.
Can you turn off the radio before going outside, and then testing to see if you can get GPS co-ordinates? (refresh GPS to get co-ordinates). It will take about 1 minute to get a GPS lock in a clear wide-open area. This will prove that Bold is capable of both native GPS *and* assisted GPS -- best of both worlds.
GPS and aGPS are both the same thing with equal accuracy (just different speeds of accurate locking), while antenna triangulation is often inaccurate. (These are all 3 different things)
For other readers -- more information about what "ephemeris" is, I wrote a
GPS FAQ -- GPS versus aGPS versus AntennaTriangulate (all 3 very different things)
As the Bold uses a Sirf III chip, I am betting that it's capable of both native GPS and assisted GPS. I just want to confirm that my hunch is correct.
