agps can get a general idea where you are based on cell towers alone, not from triangulation but from a database that the cell providers have
OR it can take satelite signals and get an exact lock.
Some qualifications here: when talking about aGPS, you should at least mention gpsOne, which is the standard we are using. All Sprint phones use gpsOne chips, even BlackBerries (despite some people foolishly claiming SirfIII just because it does standalone).

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.
That is what we are dealing with. Now, I don't see any mention of an internal antenna, but I believe in the msm65/7500 data sheets it may.

OTOH, the HTC Kaiser is well known to have "standalone GPS" but it in fact uses gpsOne (msm7200) and from the FCC photos, I can't find its antenna (any one else?, although you can plug into the back, so maybe there...)

This comment about Sprint "sure as hell isn't going to hand over something they can charge money for it" is totally false. I think it used to be very true though, but Sprint is giving up on it and moving forward.

For one, the Windows Mobile 6 Motorola Q9c on Sprint has free, standalone GPS on it. It can use Google Maps, Live Search, etc.

Number two, it begs the question: what the hell is Sprint and HTC saying when they say the Mogul (and Touch) are getting a ROM upgrade to "enable GPS on the device"?

(also, if the 6700 was going to be hacked for GPS, Colonel would have done it already )

Thanks for the effort. I have no idea what it means. lol

We'll just have to wait till Sprint/HTC roll out the update in Q1 for the Touch and Mogul and see what it does.

It would be very interesting to do three things
  1. Open up the Moto Q q9c and see its guts: msm7500 or sirfIII? I bet the former.
  2. Does it have an internal antenna?
  3. Does the Sprint Touch have an internal antenna?
