I just upgraded from 4.7.0.75 to 4.7.0.148 through DM. After rebooting I lost my connection to our BES, email calendar and contacts. This update was not pushed from the server. The server still shows my storm active, but I can't reactivate. Anyone have a solution???
All that needed to be done for my instance was to reconnect the phone to device manager. Something didn't complete with the update of my O.S. After that everything came flooding back.
