Make sure your Windows Mobile device is updated to deal with the upcoming DST changes going into effect this weekend! From the T-Mobile site, though I’m guessing it applies to any Windows Mobile device:
From your PC:
Go to www.microsoft.com/windowsmobile/daylightsaving/default.mspx using a computer that is connected to your device with a USB cable. Follow the on-screen instructions to download and install the update.
From your phone:
Select Windows Mobile (http://www.microsoft.com/windowsmobile) from your list of favorites. Follow the on-screen instructions to download and install the update.
T-Mobile was nice enough to text message me regarding this. 🙂
