Perhaps I've misunderstood the technology but I don't want my phone using airtime to find my coordinates. If that's not the case then ignore the non A-GPS comment.
EDIT: This is what I'm referring to:
Quote:
aGPS is not some monolithic, written-in-stone-standard. In fact, Qualcomm, who makes the most popular aGPS chips (called GPSOne) has four different possible configurations for aGPS. How aGPS is actually implemented on the device appears to be up to the device OEM/cellular carriers. These four options are:
- Standalone - Your handset has no connection to the network, and uses only the GPS satellite signals it can currently receive to try and establish a location.
- MS Based - Your handset is connected to the network, and uses the GPS signals + a location signal from the network.
- MS Assisted - Your handset is connected to the network, uses GPS signals + a location signal then relays its 'fix' to the server, which then uses the signal strength from your phone to the network towers to further plot your position. You can still maintain voice communication in this scenario, but not 'Internet/Network service' ie Web Browser, IM, streaming TV etc..
- MS Assisted/Hybrid - Same as above, but network functionality remains. Normally only in areas with exceptional coverage.
Standalone mode is important. This means you do not need the carrier network at all to use GPS and usually you can install any GPS mapping software to boot.

If the above is still true (it's from a 2008 article so it's perhaps generations old) then I want a Standalone option. I do not expect my carrier network to be available at all times and I'd like to use the feature say in the US where I don't have coverage.
