Fix your Windows Mobile clock's daylight savings data the easy way
Microsoft went and put up a web page explaining how to adjust your device's registry to fix the problem. But the instructions are really meant for developers, not users. Still, I'm not aware of any PDA or smartphone makers that have issued an update yet, so it was awfully kind of the folks at edgeblog to go and wrap the registry changes into a .cab file that you can install on your Windows Mobile device.
The file is called DST2007WM5.cab, which makes me a bit reluctant to install it on my Windows Mobile 2003SE device. That, and the article repeatedly mentions installing it on a Smartphone, but says nothing about Pocket PC devices. Not to mention the fact that this is an unofficial program that is meant to change your registry settings.
In other words, install at your own risk, but if you do, please back up your device first, and let us know the results!
