Microsoft officially announced the Windows 10 Mobile upgrade last week, and now Vodafone Australia has announced the official start of the roll-out to handsets on their network.
The update will be coming to the Lumia 640, Lumia 640 XL, Lumia 735 and Lumia 930.
Interestingly other than firmware, this will likely be the last OS upgrade being routed via the carrier for these handsets, as monthly updates should roll out to the devices directly from Microsoft afterwards.
The update will likely only come to a small percentage of devices on the 25th, with increasing numbers receiving the update over the next week or two.
