I am going to post here in hopes of receiving help...and to assist others that may encounter the same thing. (mods - if this should be a separate thread, please move it or ask me to do so)

I run WM5 with wireless sync. My extra computer running wireless sync is a Windows 2000 machine with outlook 2003. I took these steps to update:
1. Updated my machine and outlook with the typical MS updater.
2. Updated my machine-side wireless sync system per the wsync email.
3. Updated my i730 with the MS DST patch and updated wireless sync client per the wsync email. This includes the "change your timezone, save/ok, change it back" step.
4. Verified that my Outlook 2003 calendar looked ok for next week (minus those that had sent me meeting requests and not yet performed their DST patches)
5. Performed a wireless sync
6. Verified that the online wireless sync web calendar looked proper for the week of 3/11 with same caveats from (4) above

All of my appointments look fine within Pocket Informant 2005 except for a handful of meeting requests that originated from me and were updated properly with the MS DST patch (i.e. my Outlook calendars are fine, other people's were updated fine, and online verizon wsync calendar is fine). I tried to force wsync to refresh all calendar items from my computer. It updated all appts, but I still have the display problem.

Would appreciate any suggestions that people have. I also have a ticket open with Pocket Information support.
