Nokia has tweaked PC Suite 6.5 to fix the Outlook sync issues apparent after its initial release. Download the April 28th version here.
PC Suite bug fixed
I was hoping this would fix the bug that locks Outlook to the PC Suite sync once my Nokia has synchronized. I have both a Nokia 6620 and a Palm Tungsten T3. When I sync with the Nokia first, any subsequent sync attempts with the T3 don't sync with Outlook. If I sync with the T3 first, the Nokia will sync fine, but once the Nokia has sync'd, the T3 is locked out again.
I guess there was another bug that they fixed. It would be nice if there were some release notes somewhere...
