Australian residents tied to Vodafone, there's a piece of good news for you. If you happen to be a proud owner of the Lumia 930 or the budget-friendly Lumia 630, you'll be happy to know the carrier will start rolling out the Windows Phone 8.1 with Lumia Denim starting March 14th -- it's already Saturday on the other side of the world so the update should commence in the next few hours.
It's worth mentioning that updates are rolled out in phases so it may take several days for it to reach all device owners. Alternatively, you can manually check for the update as well to see if the update has arrived or not.
These are not the only Windows Phone handsets the carrier has to offer; it contains a number of Windows Phone in its product portfolio, including the Lumia 1320, Lumia 625, Lumia 720, Lumia 820, and Lumia 925. All these devices are still listed as "testing in progress" but since let's just think positive and hope the carrier will roll out the latest update for the above mentioned handsets soon.
