BUT....... I wonder if the 5725 model would work then? It says it has "gpsOne", and according to Sierra, gpsOne can operate in 4 modes:
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.
So, it appears that with this "gpsOne", it can operate in GPS mode only. I wonder however, if the card must be activated for the GPS to actually work? Maybe it's experiment'n time???
I just checked, and the MC5720 also supports gpsOne. Hmmmmmmmmm
