Google's improved how its calendar and email services interact with Windows Phones running the Mango update. Users can now cram up to 25 different calendars into the Metro OS's built-in calendar app. The setup's not exactly seamless; you need to navigate your Windows Phone to the Google Sync page, login and check the boxes found there. While testing on our phones, although one device was able to immediately sync, the other couldn't pick up on our multiple calendars. We had to delete and re-assign our Google account to the phone in order to get it working. However, once we did, the Metro styling lent itself well to multiple calendar listings, with the ability (like the web-based Google Calendar) to assign colors to each.
At the same Google Sync page, you can now choose to enable the "send mail as" feature if you're using multiple addresses, with the option to delete unwanted emails instead of archiving. However, aside from replying from the same address that you received emails to, we haven't discovered a way to assign new mails to our multiple guises. We were able to send messages through our own Engadget mail account, although that's then used on all future missives. Despite these rough edges, it remains a welcome bit of extra functionality. Are we still longing for a dedicated Gmail app? Definitely. We just hope those devs don't drop the ball.
