  • whither the GPS bug?


    Users on Apple support forums are still complaining about loss of GPS functionality after upgrading to the 3.0 firmware release.

    As TUAW notes, some users are getting their iPhones replaced, even though Apple is not acknowledging that a bug exists. Some people have had success after rebooting their phone, or disabling 3G. And there have been reports that the problem went away after upgrading to 3.1 firmware.

    So a problem that may or may not exist can either be fixed with rebooting your iPhone, turning off 3G, replacing it with a new phone, or upgrading.

    I'm curious if any members out there have experienced problems with their GPS function, and how or whether they fixed it if so. I have noticed my blue dot creeping around of late, which reminds me more of my old Brickberry's cell triangulation than true GPS. But I'm not a heavy user of Maps.

    What are your experiences?

      Takes forever to lock on sometimes and is sometimes a little inaccurate. But most of the time it's fine.

      Well I didn't know this was a problem others shared. I use maps all the time and I agree it felt the same as on my first gen using triangulation but I thought that's just how the new gps was thinking it wasn't really a true gps. Whatever it's close enough for me most of the time that it's not really a big deal to turn the phone in over. It did throw me off walking around the streets of San Francisco trying to use maps with gps and compass and it showed me walking in the opposite direction for about a block until it would refresh to the correct location. It wasn't constant but happened occasionally.

      Just yesterday cruising around with TomTom app. GPS wouldnt even pick up a signal... restarted phone and used Sygic and the GPS was running smoothly, sometimes the signals are really bad and have no correct directioins but you cant expect the BEST from an iPhone over an actual GPS device, is that right?

      First of all Im in Puerto Rico, and GPS have never been awesome here, but right now Im on 3.0.1, iPhone 3G JB and its very acurate, the blue dot is in my neighbours house, Im guessing thats good enough.

      I use my 3G[S] all the time for map applications and such because my g/f and I geocache using it. I usually see it say an accuracy of like 56 ft when I'm outside which is pretty good considering the limitations of civilian GPS and military GPS. I don't recall the exact limitation, but I want to say like 20-30 ft was the best we were allowed with any device. My g/f has a 3G and she doesn't have problems either. She uses maps
      a bit because she gets lost alot lol.

      Ehhh I hardly ever have had GPS work on my 3GS. It worked great on my first gen though. You guys think I could get them to swap it out? I just thought it was jailbreak related. Now that I realize it is widespread I might take it up to an Apple Store. Sometime.... I have two but they are both four hours away.

      My iPhone 3GS and my wife's 3G (my old phone) both are the worst GPS devices ive ever seen. With TomTom i can only get a poor signal that locates me within about 25-30 miles of my actual location, then doesnt move me at all for 10-15 minutes at a time.

      When using google maps, sometimes i get a good lock on where im at but it never lasts long, and for the most part, it shows me very very very far from my actual location.

      Before 3.0 when I had my 3G, the GPS was working fine, then I installed the 3.0GM before it was released and have been having issues ever since. Even with my brand new 3GS, that was one of the first things i did when i got back to my car from the AT&T store, i turned on google maps to check the compass and i showed me miles and miles away from my actual location, with a HUGE range of error.

      when I got the 3GS with 3.0 I noticed a loss in functionality in GPS. I deliver pizzas sometimes at my pizzeria so I am a heavy maps.app user. Not that I need the GPS blip, but it helps a lot.

      I'm jailbroken though, and don't want to update yet..

      Yeah me and my friends are experiencing that problem on our jailbroken/unlocked iphone 3g. we all used the same software to unlock and jailbreak the 3.0 software so prob thats why? All of our gps would not lock on.

      Living in Greece where everything has an error margin the only GPS difference I found upgrading from 2.2.1 to 3.0 on my iPhone (3G) is that when in my house it shows my location two blocks away. However on 2.2.1 I didn't even get a signal inside...

      TomTom reception is bad (only one I tried) but Apple Maps give extremely accurate position (slightly better I guess from 2.2.1) and xGPS has been a lifesaver.

      There are many factors in GPS signal reception but I think OS 3.0 isn't one of them...

      Things defiantly got worse with 3.0 but do seem better with 3.1

      If anyone has a blue circle round the blue dot, that means it is using triangulation and does not have a GPS fix. For a first fix you should go outside with a clear view of the sky and wait - a first fix can easily take 10 minutes or more.

      Turning 3G off for a first fix helps but it should be turned on after getting the fix otherwise SatNav programs will not be able to get a fix when moving.

      The GPS in the iPhone is definitely one of the worst in any phone - it has to be queried rather than supplying a stream of info and does not provide basic nmea data such as the number of satellites found, let alone the strength of signal.

      As for why the picture of Wally is relevant? How are you supposed to find him without GPS?
