Hi, we've done some work to make our service compatible with the N900 and at this point I think it works quite well (sadly we don't yet have an actual N900 to test with). I'm also interested to know if the N900 can do multiple calendar sync like the iPhone. We have code that merges all the user's (selected) multiple calendars for devices that don't support multical. Currently the N900 is treated as a single calendar device by our code. I we can confirm that it does do multical (the search for the answer to this question was the reason I found this thread btw), then we'll change the device type in our service. Register for a free acct at www.nuevasync.com (use the free trial option to enable email and tasks sync testing). Please send reports of any problems to our forum (I may not see replies here quickly), or via our support system.
