Vodafone Australia will begin to roll out the Lumia Denim update to owners of the Lumia 630 and Lumia 930 smartphones on Saturday, March 14. Since it is already that date in that country as of this writing, we can safely say the rollout should begin in just a few hours.
The news comes via an update on Vodafone Australia's software update website. This is good news for owners of the Lumia 630 in particular. In January, the carrier said that smartphone would not receive the Denim update due to "issues found in testing". It would appear that situation has now changed.
Keep in mind that even though the Denim rollout starts soon for those phones, it might take a few days for all owners of the Lumia 630 and 930 on Vodafone Australia to get the update
