Back in January, we discovered that Windows 10 Mobile's discharge to more established Lumia handsets was postponed and would likely occur in late-February. Microsoft had sent an email to its accomplices, probably bearers and conceivable OEMs taking a shot at Windows 10 Mobile gadgets, affirming the postponement.
On the authority Microsoft Mexico Facebook page (spotted by means of Winphonemetro), an organization delegate said that Windows 10 Mobile was set for discharge on the 29th of February. Remember that occasionally these agents are misled, so until we get an official declaration from Microsoft, we're marking this as gossip. We'll have more on this as it creates.
This of course does not apply to the Lumia 550, Lumia 950, and Lumia 950 XL, which already comes with Microsoft’s latest Windows 10 Mobile operating system. If you cant wait for the official roll out of the update, join the Windows Insider program (if your phone is eligible) and snag the latest build now!
The list of devices in First Wave are as follows
• Lumia 430
• Lumia 435
• Lumia 532
• Lumia 535
• Lumia 540
• Lumia 635 (1GB RAM)
• Lumia 640
• Lumia 640 XL
• Lumia 735
• Lumia 830
• Lumia 930
This seems to be an official statements from Microsoft, because comment is still available there (not deleted). But if you remember well, this is not first time that we get the date of release.
Hope so this time Microsoft will release Windows 10 Mobile on 29th February.
