I downloaded the beta and started to play with it. The first thing I discovered is that you must have Microsoft Outlook installed, because Itunes will only let you sync from Outlook or Yahoo Address Book. I did have a copy of Outlook, so I installed it and I made the mistake of trying to link it to yahoo mail. Some how it made a mess.
So I tried another machine, since I could not get out of the problem of "files not found", even after I un-installed and re-install.
Once I installed outlook and Companionlink on the other machine. I had to open Itunes and make sure to select to sync with outlook, and then I ran the Companionlink sync program. Every thing synchronized well, I have all my calendar and contacts in both Outlook and the iPhone.
Two problems.
1) the sync is manual.
2) The sync took 1 hour to copy the entries. It actually selected every entry on my calendar going back to 2001 and copied them into the iPhone and outlook. which was not that bad if it only had to do it the first time, however every time I sync it reads all 3650 calendar entries again. Even if you only made 1 change. So it took another 30 minutes to sync 1 new calendar entry.
However it is the only thing available now. I sure hope Apple decides to support Lotus Notes. all my friends at work will be getting iPhones if they could replicate their calendar from Lotus Notes.
I have a 14 day trial period I will continue to play with it. However the Apple thru iTunes is the right solution.
