Will Windows 10 Mobile launch today?

Windows 10 Mobile could be launching today, according to reports.

The operating system's rollout onto legacy devices running Windows Phone 8.1 would begin on 17 March, according to a VentureBeat article written by notorious leaker Evan Blass.

The report, which cited a source close to the matter, said that the update will initially be delivered as a 'pull' model, meaning users will need to trigger it manually from the phone's update menu.

Microsoft will use push notifications to promote the new OS at an unspecified later date, Blass said.

The tech giant is widely expected to deliver the update in batches, meaning some phones will get the update before others. This likely means that the company's most widely-used models will be eligible first.

This information has reportedly been confirmed by T-Mobile Croatia. The carrier confirmed that customers with select Lumia devices will be able to initiate the update from today, with more devices following in subsequent waves, according to NokiaMob (translated).

Microsoft itself has lent further credence to these rumours by publishing a similar list of phones that will receive the upgrade; a list which matches closely with the one sent out by the telco.

Both agree that the Lumia 435, 535, 635 (1GB RAM model), 640, 640XL, 735, 830 and 930 will be eligible, with Microsoft's list also adding the Lumia 430, 532 and 540. Interestingly, however, the flagship Lumia 1520 appears on T-Mobile's list, but is absent from Microsoft's.

None of these details are officially confirmed, however, and Windows Phone users will have to wait until Microsoft officially unveils its plans to find out the details for sure.
