KB 923953 "How to configure daylight saving time for the United States and Canada in 2007 and in subsequent years on Windows Mobile-based devices" *helps* you patch up your smartphone to deal with the upcoming DST change.
WARNING: the fix is a reghack, so standard waiver applies. "Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk."

Watch this space, I'll post if a user-friendly patch method becomes available on Technet.
