I’ve recently got a, and for all the nice features the phone and Windows Phone 7 has, one annoying feature was the lack of multi Google Calendar support; when you add a Google Account to the phone, it only syncs the primary calendar associated with the account; I have 4 or 5 main Google Calendars, and subscribe to a number of iCal feeds too, so this really didn’t provide me with the full Google experience I need.
I discovered there was a way of getting multi calendar support, involving a desktop PC, mucking around with browser settings (and user agent settings), which allowed you to access a Google sync configuration page where you could add multiple calendars. This worked, and I was really happy.
However, Google have now confirmed that if you access the m.google.com/sync page direct from your Windows Phone (using IE9 on the phone), it will allow you to select your WP7 device, and then add multi calendars to be included with the next sync.
Once done, go to the Settings / Accounts, press and hold the Google account, and select Synchronise. If this does not bring down the additional calendars, you may need to remove the Google account and add it back again. Also, once you have done this, you can go into the Calendar settings and change the colours of each calendar to bring them closer to the colours you have adopted within Google Calendar directly; that way a quick glance at your calendar, and you should know what’s going on.
So far this has been the only “showstopper” that has stopped me enjoying the device; yes, it’s not perfect, and there are still lots of little things for Microsoft / Nokia to sort out, but now allowing multiple Google Calendar support is a good start (for me!).
Update: I’ve removed a minor comment regarding Nokia Drive, as Nokia are kindly in contact with me around my comments with the app.
