I recently upgraded my curve from 4.3 to 4.5. I do have a problem with the "Where I Am" feature in Blackberry Maps. At first it worked perfectly. Now it works sometimes, but most of the time it won't find my location. I do have the GPS location set to on. The upgardes like GPS navigation, Docs To Go and HTML email are wonderful. I appreciate any suggestions you have for the "where I am" problem. Thanks
