So you just got a brand new BlackBerry, you slap on Foursquare, let it detect your position, but notice that it’s taking forever. You make your way through the options menu, select the ‘GPS’ menu and start switching ‘location on’ to ‘location off’ back to ‘location on’, then from ‘enable’ to ‘disable’ back to ‘enable’. At this point you might make your way back to Foursquare, realize that you’ve had enough patience to deal with the nonsense and run to your service provider claiming that your GPS isn’t working. Hold the phone.
