ortiz- the answer to your question in the other thread, is that switching the timezone to anything but yours, and then back to yours, causes the device to use the new timezone table provided by the patches.

For my problem reported above, i can confirm now that Pocket Informant has nothing to do with it. Wireless sync calendar on my wsync website is proper, but wireless syncing to my device is leaving some appointments out of whack. The folks at PI said that they have been hearing about LOTS of problems with the DST updates on devices. Ugh...
