  • GPS (ish) Comes to the iPhone!
    Navizon, which just showed up in Installer, is an assisted GPS system which triangulates your location based on the cell towers you are near. Some have reported success with this, while others have not.



    I am on T-Mobile, and it is giving me an error: "Unable to locate any known cell towers". Could it only work with AT&T? Or am I just in a lame place? Your thoughts... Please post your area along with your results.

    UPDATE: Works fine on T-Mobile, assuming you're in an area it knows. Not sure yet where it gets it data, as far as where it will know and where it won't. But I went down near the Tampa International Airport, and it definitely knew that area. So it works on T-Mobile!

      Got it installed but doesn't work in Medford, OR on Edge or Wifi.

      I think I found the problem though.
      If you log into their website, almost every page is "down."

      From reading the site I believe it gets its information from Navizon users running wifi, cell, and GPS on a device.

      On the website it looks like you need two programs if you phone doesn't have gps Navizon and Virtual Gps. Is this what is causing everyone's problems- or am I shooting in the dark?

      Don't think so. That is for something else. Works fine for me, just doesn't seem to recognize a lot of areas.

      I'm in Honolulu, Hawaii and it seems to fine, just a little off positioning. I'm with AT&T and my phone is also unlocked. Right now I'm at work on the 24th floor on WIFI. This is my first time trying it. Works with WIFI but not with EDGE (at work) so far, will try EGDE at a different location. Takes about 7-10 seconds to locate me. GPS has me position out in the streets on the sidewalk about 100 feet away from my building. Not bad considering I'm in Hawaii because we don't even have GPS in our cars over here or even use GPS...for the most part...surprised it even works.

      Wifi - Off = Cannot find cell sites / towers
      Wifi - On = Cannot find cell sites / towers

      No go here.
      Ill try other spots in the city, but ... this kind of stuff makes me wonder why I even bother installing such apps..

      In San Francisco bay area, works fine finding my locale via Wi-Fi (drove around and tried many locations), but has yet to pick up anything over EDGE. Running version 1.0.1 with same situation.

      Triangulation off cell towers is how this new Mobile-911 service is supposed to work, so it certainly should be possible for an enterprising programmer to pull that function out of the iPhone. Sounds like things are a bit off right now.

      It also is not handing over my coordinates to Maps when I tell it I want directions TO or FROM my current location. If I have to type the coordinates into Maps, how much time am I saving?

      And I saw on the Navizon corporate blog that the plan is to give this away for 14 days, then charge $24.99 for the app.

      PF,
      It says that the WiFi must be turned ON (but you do not need a WiFi Network) in oder for this to work. I think it is basically doing the triangulation
      using a DB that is LEARNING as it goes on their server and just putting your location on a Goggle Map for that location.

      Maybe it will be possible in the future to go over the phone line itself to do this.
