    with a stock rom, you have 3 options.
    1) wireless networks
    2) GPS SAT'S
    3) (i believe) cell tower assisted (or something like this)

    with this rom, we only have the first 2 options.
    what happened to the 3rd?

    Ok... go F yourself.

    No seriously, I know what you're talking about. GPS Assisted or whatever. From my understanding it isn't an option to select but is automatically enabled when you enable GPS.

    aGPS (the third option you speak of) is basically just GPS with the wireless network assistance. By enabling wireless network (option 1) and GPS (option 2), you are using aGPS.

    To further my post: I never understood why there were three options in the first place. The only way to get location is from GPS, the cell towers (if Google or Verizon knows the exact location, I am not sure which provider is being used for this), or location aware WiFi networks. WiFi and Cell Tower location are bundled under "wireless" and GPS has an option as well. I suspect that they disabled the third option, because it is rather stupid to only use GPS and not aGPS.

    Not too sure how I feel about this. I have been noticing that my location is sometimes off by several 100 miles due to wifi networks being located incorrectly.

    Before I switched to Liberty I never saw this issue. I know without Liberty the third option could be left on without the GPS and this would allow you to be located within a few 1000 meters due to cellular triangulation (the reason for the large circle in google maps).

    I could be off but I feel like we need that third option.

    Just noticed that was gone in the 1.5 update prior to seeing your post. Whether that makes a difference, dunno, but the concern I have is GPS functionality. I was just getting ready to head out the door so wanted to test Google Navigation and though I can find my location SOMETIMES, once I get directions then enable Navigation just sits there and does nothing (i.e. doesn't load route). So its as if GPS is somewhat crippled.

    FAA issues aircraft GPS disruption advisory because of DOD testing -- Government Computer News

    Not sure where you are but if you are on the east coast this could explain it. My GPS is working flawlessly. Really miss the cell triangulation though.

    Bottom of the article states "A spokesperson at the FAA said that there will be “no impact to ground vehicle GPS.” That means that smart phones, automobile guidance systems and other civilian GPS functions will not be affected by the tests."

    Whoops. Sorry. Missed that.

    Still, anyone got any reasons as to why the cellular triangulation option is missing?
