A few days ago, a report from Italian blog WindowsBlogItalia emerged stating that Windows 10 Mobile would begin rolling out to older devices on Thursday, March 17. Since the report also said that Microsoft would announce it on the 14th, it seemed like another dead end rumor, as we"ve seen so many times.
Today"s report comes from popular leakster EvLeaks, now at VentureBeat. Even Blass was also the one who reported that Windows 10 Mobile would ship to older devices in March; however, to be fair, that wasn"t exactly a hard prediction to make after the February 29 rumor turned out not to be true.
While WindowsBlogItalia"s list of devices to be upgraded tomorrow included Lumia 535, 636, 638, 640, 640 XL, 830, 930, and 1520, Blass says that the list of devices remains a "closely-guarded-secret".
Nevertheless, while Microsoft may begin rolling out Windows 10 Mobile to older devices tomorrow, the upgrade will require carrier approval, so it"s likely that it will only be unlocked phones rolling out the OS in the beginning. There was originally to be two waves of upgrades, the first wave coming to newer devices, while older devices would be upgraded three months later.
As we"ve stated before, there will be no device-specific firmware bundled with the Windows 10 Mobile upgrade in the way that Lumia Denim was bundled with Windows Phone 8.1 Update 1. Users that simply can"t wait for the official upgrade can do it through the Release Preview ring of the Insider Preview and get the exact same bits.
Also, users of Windows Phone 8.1 devices have not been able to try out the new Redstone builds just yet. Gabe Aul has stated that this will change once those devices are upgraded to Windows 10 Mobile.
