I did test the Google API and it worked pretty well, I also did compare with the CellLocate by UBlox and the accuracy is fairly similar (at least in the two locations I tested in Italy). If you are interested, feel free to contact me.
I was wondering, how it is possible that any android or iOS phone can locate their phone without using the GPS and using the 3G? the accuracy for them is really good…do you have any idea what do they use to get as such accurate location?
thanks in advance for any help!
