Nokia just announced on their corporate blog that the latest updates are being sent to Nokia Lumia 900 owners in the US and Canada starting today.

Here are the important details from their blog post:

Please note: For this particular update, there will be three updates to install and the entire process will take up to 30 minutes to complete.

You’ll see the following messages on your phone:  “Success! Your phone has been updated” followed by a message “An update is available…”.

There is no need to tap “close” or “ok.” The phone will continue to the next update automatically. This will happen three times before you should disconnect your phone.

For US Lumia 900 customers

This update brings the following enhancements for US Lumia 900 owners:

  • Flip-to-silence feature
  • Camera performance enhancements
  • Battery performance enhancements
  • Startup sequence performance enhancements

For Canadian Lumia 900 customers

This update brings the following updates to your Lumia 900:

  • Flip-to-silence feature
  • Support for Contacts Share app, to send and receive business cards as text messages
  • Proximity sensor performance enhancements
  • Removes purple hue which affected some phones in low-light conditions
  • Startup sequence performance enhancements
  • Camera performance enhancements

It looks like the Canadian users are finally getting the purple hue update which we received in the US a few months ago.

So off to your Zune software, plug in your Nokia Lumia 900 and hit the Update Settings page to download your update. If you are like me and it is not showing the update then try, try again!
