I have a brand new 8100 and I was able to synchronize my calendar, task list, and memo pad to the device (from my PC), but cannot sync my address book. The Intellisync software simply gives up saying that "it cannot write to the device." I'm pretty familiar with Intellisync and I set it up to sync my address book of Outlook Express. Has anyone experienced this? If I can't sync my address book, I'll have to go back to my Treo
