If this is true, I guess the device time would be correct even though the DST settings stored in the registry are incorrect. Question is: would not applying MS's registry settings have any other negative affect? We manage hundreds of WM devices in the field (including many i730s) so whether or not to deploy the CAB is a major decision. Thanks for a great forum.

Actually no. Pocket PC devices do NOT look to Verizon for Date/Time information. It is kept on it's own, and synced and updated when connected to the computer. If they make a change in their tower, it will not affect you. This is because of the stored calendar items on the device. If you changed a time zone and made an appointment, then the phone wouldn't know which time zone the appointment was part of or which time zone it should be scheduled in. So the PPC's need you to manually set the time zone and time so it doesn't mess with appointments.

I did a big discussion of this at one time, and I know there are LOTS of discussions on this online. Your i730 and other Pocket PC devices will NOT automatically update when time is changed, other phones on Verizon's network will, but Pocket PC devices don't receive the update from the service provider, which is why they released this patch information.

Yes your time will update when connected to the computer, but it also might try changing again when it "thinks" the time should be updated again, so you might get a double change, and it won't fix itself until connected to the computer again.

It would be best, as advised by Microsoft (since they know more about there devices than Verizon does), to run the update, either in your own created CAB, or the one I provided...
