so it says sorry don't know where you are.
1) If it does not have 3G, it does not have a built-in GPS
2) All iPads have wifi - they do not make one without it.
3) If your iPad does not have a built-in GPS (see point #1), it will not receive a GPS signal. The Telstra wifi does not provide GPS data - it is for wifi only.
What you are attempting to do is secure a position using wifi location. All this will provide you with is a very approximate position. Essentially, your position will be that of the location of the closest IP address node in the network for which a position is known. It will never be close to your actual position unless your actual position happens to be right next to a known wifi access point.
And this can be VERY far away from your location. For example, right now we are in San Blas Panama
hooked to the internet
through 3G using a device similar to your Telestra. Our "wireless" position is currently located in Rancho Cucamonga California
, which is the nearest known IP node in the routing structure.
I'm sorry to say, but your current
setup will not work
for your needs. You will need to get an external GPS for your iPad, like suggested earlier.
