  • 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!

      Actually thats not true at all.

      GPS just means it uses satellite signals to track the location or position of vehicles or vessels on earth. This is a quasi-GPS system (Global Positioning System) which uses cell towers an WiFi locations to discern your location. It finds your location, NOT gives directions.

      You're talking about the Google Maps application on the phone, which is what gives you directions.

      And no, GPS doesn't have to have vocal directional prompts to be GPS. Just a lot of the devices do.

      J.S.
      actually gps gets your location using a group of satelites. Certain equipment converts your latitude and longitude to auditble instructions.

      This is not technically gps because it relies on cell towers and wifi.

      I tried it on the road twice today; both times around my hood; once in Foster City, CA at a strip mall; the other time at a different strip mall in San Mateo. Both times the pull-up was within a block. The first time was via cell towers, the second with wifi. I haven't been able to get it to find me at home though.

      As for the $25 charge, as long as this is a one-time cost, I woulqd be willing to pay for this. It sounds like this is a situation where they use the fee to pay bounties to folks to identify the wifi spots for the basis of its maps. I would actually sign up to do this, but my iphone isn't GPS compatible.

      Location: Long Beach CA
      It found me but I think it just scans for the nearest Cell site.
      Cell site was found north of my location about 1/2 a mile.

      Update!

      It found me when I was near a Starbucks
      WiFi on but not connected to any, it seems that it found my position by WiFi even though I am currently on EDGE
      about 100 yards off the mark
      Not bad!

      I'll try it from Kearny Mesa (Work) today...maybe the "Hi-Tech" area there will make it work...

      Funny thing is, on "FieldTest.app"...even in South County San Diego...I am getting 8-10 repeaters that are relatively close by...but those towers are probably not in the Navizon database yet...

      I don't see how they are going to manage ALL of the repeaters that cover the WORLD in their server...but then again, maybe they have all the money in the world to buy 1000000000000000000 terabyte HDDs servers...unlike us poor people that only have 7.33GB in our lemonphones...lol

      I install this pseudoGPS app last night,restarted iphone, start the app. and almost fried my phone. Screen locked up with message that cannot locate due to network problem wi-fi and cell. But more scary part that I couldn't turn off the phone, home button didn't responded ether, and screen constantly on, and iPhone getting hot. At this point I was waited 15 mins and then tried to make a hard reset, but phone all of a sudden returned to home screen and became cold( normal temp). Very scary....

      No towers/nodes for me at work at Ft. Belvoir, VA or at home in Fairfax, VA. Oddly enough, one of my coworkers has no problems connecting here at work. Bizarre....

      Understood.. BUT.. What's the use of GPS without vocal and enroute directions??? Easier to just use Google Maps/Directions through Safari (And more accurate).
