Nowadays, all mobile devices come with GPS Navigation tool in them. Share your experiences of that feature in your mobile device.6 months or back, i first used the GPS feature in my iPod Touch 4G. Since i had no connection of Wifi when on the go. I surfed the map all along the route in my home, so that it will be stored in cache. The GPS feature in the iPod was not that much satisfying, as it did not pointed my exact location while i was traveling. The pointer used to disappear and appear every now and then. Moreover, the mpas in iPod Touch wont load in Touch without Internet(Wifi). So, that was my experience while i tried to use it. Neither did the map rotate while the vehicle rotated.Which one do you think is the best mobile device providing good GPS Navigation. BTW, have you used any hacks to get this cool?
