    Guys I have a question, I have a HTC Hero with built in GPS, I noticed that when I use the HTC HERO as a hotspot the ipad gets location only via triangulation, and it's less acurate than using wifi on my home.

    Is there any way via bluetooth or wifi to be able to transfer the real GPS data and internet from the phone to the ipad? and not only the internet data?

    I just don't want to buy the ipad 3G just because of the GPS, its worth it but If I can go around and use my phone as the GPS data provider I wont need the 3G version.

    I want to implement this ipad on my car, that's why I ask.

    OP,
    I have wondered this myself, as I will be inheriting an iphone 3g when the new ones come out. I don't have the need for 3g on the iPad, but would like to have the option of working GPS. 130$ (price of 3g/gps) + cost of good GPS app with built in maps = more than I wish to pay for it.

    It seems unlikely, and from what I can find in regards to tethering from an iphone to a laptop running windows or OSx, it isn't yet been made possible to transfer a gps signal.

    My only thought is since the wifi model can mimic gps by using router locations, would exact location data constantly update on your phone (which would be tethered), and in essence provide a pretty close estimate of your location to the iPad?

    RoqyBT can do this on jailbroken ipod touches when used with actual bluetooth gps.

    you'd need to see if there was an app for your htc that will output the GPS via bluetooth.

    Ive tried this with my nokia symbian phone and an app but the output is not compatible (yet)

    no it will not work.

    the way the wifi position works on the ipad is that there is a database of wifi access points gathered by skyhook wireless.

    they essentially drive around and plot wifi access points on a map and assign a location to each one.

    so the idea of an iphone or 3G access point providing GPS data is incorrect. skyhook would have had to insert the position of your iphone running mywi into their database. which would not help because the access point is always being moved around.

    some companies like tomtom have developed an external GPS receiver that connects to the dock connector. this will provide GPS positioning. as for maps the 3G modem would provide map data for google maps or some navigation apps will have maps stored locally on the device so no internet connection is required.

    does anyone know if there is a Bluetooth profile for external GPS units, like the Pharos BT GPS receiver?

    Is there a way to get the 3g from my sony Aino to work with the ipad , as in creating the 3g into wifi ?? I can power internet on mac's with it via blue tooth so was wondering if anyone knows a way of doing this and has an app name or something (preferably cheap or free) and for it to work with the ipad if possible?

    There isn't any Bluetooth Profile. Bluetooth GPS devices typically use SPP (Serial Port Profile) along with software or a driver that you have to install on the computer you will be connecting from.

    As somebody else pointed out above, there are (jailbreak) third-party apps that can do this with specific Bluetooth GPS devices. The software has to be written to accommodate the specific device, because there is no standard way to format the data over the emulated serial port.

    It should be possible to write non-jailbreak apps as well, since Apple has a developer program for devices that communicate via the dock or Bluetooth. For example, the TomTom app can use their own external GPS receiver connected through the dock.

    You are dreaming if you think the iPad is going to use the GPS in your phone, though. For starters, you phone would have to expose the GPS through Bluetooth, which is pretty unlikely. Then you'd have to have an app that supports your particular phone, or at least the data format that it uses over the Bluetooth connection.

    At that point I'd just spring for the 3G model.

    Ok today I did a test today with my HTC HERO phone providing the wifi connection to my ipad while I was driving, and google maps GPS position was was working but not very acurate. I drove on a empty street with no houses around, the ipad was only receiving data from my phone only.

    I have GPS MOTION X, and GPS MOTION DRIVE, both received GPS signal but it showed as triangulation only.

    I definitely want a real GPS on my ipad, so I guess I will be selling my wifi and getting the 3G to get the real gps chip on it.

    ACTUALLY.... doing something like this wouldn't be all that terribly difficult....

    Write an app for the iPHONE the hooks into the Location service. (which is stupid simple) and using the Game API allows the iPad to connect to the phone via Wifi or BT. Have another app on the iPad that also makes the game API data connection to the phone. Phone sends data across to the pad for the GPS lat/lon/alt info.

    The problem is that there's no way to push that INTO the IPad's Location Service API's, so any app that was written (like the Map) to use the standard location service API won't see the data coming across. But custom apps written to connect to the iPhone and get it that way should be able to do so just fine.

    Whether Apple would allow them is another matter entirely...

    we need the dev team to start working on the jailbreak and create apps that could make this work :)
