I had the same problem also...I uninstalled and reinstalled, GPS was set to on and still had same problem..google and bb maps worked fine..Uninstalled Poynt and installed Where and it worked fine..I dont know why Poynt did not work for me, but I really like Where....
I uninstalled the app... and when i rebooted, my handset indicated "uncaught exception" error message along with other ones and it removed my icon for msgs.. Can anyone help?
