Hi. I'm a Mechatronics Engineer, a produly owner of a BB 8130 with Iusacell Carrier in Mexico. I also have the problem of disabled GPS.
The "Assisted GPS" or the "GPSOne" works with the triangulation of the antennas of the network. You are right on that. All relatively new phones can do that. But some Blackberries do have a complete GPS chipset. Check at the BB Website, and all those that say "GPS" in specification, refer to an actual satellite-working chipset.
In the case of Iusacell, I paid the subscription to my carrier's Telenav version so I actually had the oportunity to test the GPS. After my subscription expired, I can only to the unaccurated assisted positioning.
Iusacell is not very good in coverage in some areas and last weekend, I drove all the way to Tampico through the Rainforest. I calculated and downloaded the route at home, with network coverage, and had my Blackberry giving me my actual and accurate position at every moment of the journey. I lasted 2 hours without network coverage once and still my Telenav was working perfectly. SO THE GPS DEVICE IS COMPLETELY INDEPENDENT OF THE NETWORK!!.
I think this problem can be hacked and I will try.
And by the way. A GPS that works without coverage is still very usefull. You can download the maps online using "gMapMaker", save them to your MicroSD, and use them with "Mobile GMaps".
