If you're a Windows Phone user who uses Google Calendar for your scheduling needs, you've probably been frustrated with the lack of support for multiple calendars. Thankfully, it looks like you don't have a reason to be angry anymore as Google announced today that it has added support for the feature in Google Sync for Windows Phone 7.5. In addition to improving calendar handling, the update lets Windows Phone users search through emails that aren't stored locally and set which email address to send from by default.
If you previously used a workaround to get access to multiple calendars on your Windows Phone, you won't be surprised by Google's method. While you don't need to change the user-agent string anymore, you still need to go to m.google.com/sync on your phone to set up which calendars you'd like to pop up on your device. It doesn't look complicated, but check out the Google Support source link below for help setting it all up.
