Those of you with Windows Mobile phones may be an hour late or an hour early to all your appointments at certain times this year, thanks to the Daylight Saving Time adjustment of 2007. What can you do? Follow the steps listed on the link.
For users who can connect the device to their Windows PC, all you have to do is install a time zone update tool, sync your device, and run the update tool. For users who don't connect, you have to manually download a cab file from your phone—assuming you have mobile internet. If you don't have internet, well, you'd better make a note to yourself that all the times are an hour off.
