Impact to BlackBerry Desktop Software
Intellisync (Synchronize) USB Calendar Synchronization
If the correct patch has been applied to the Microsoft® Windows® Operating System then calendar synchronization should continue to function normally, regardless of whether any patches have been applied to the BlackBerry® device (for example, if the user chooses to manually change the time).
Intellisync (Synchronize) USB Time/Date Synchronization
If the correct patch has been applied to the Microsoft Windows Operating System then BlackBerry® Desktop Software v4.2 Service Pack 1 is required to properly synchronize the time. If earlier versions of BlackBerry Desktop Software are used then the wrong time zone information will be sent. For example, 1:00pm Central Standard Time (Mexico) will end up being 1:00pm GMT on the device. It is recommended that this Time/Date Synchronization be disabled until the new BlackBerry Desktop Software v4.2 Service Pack 1 is installed in this case.
