AT&T is now rolling out Windows 10 Mobile for the Lumia 640. Those with the handset should be able to download and update their device to the latest release of Microsoft's OS.
Cricket Wireless is currently selling the Lumia 640 for $29.99. It has also cut the price of the recently launched Lumia 650 by $10 to $119.99.
A software update chart from Vodafone Australia shows that it has pre-tested Windows 10 Mobile for its versions of the Lumia 630 and Lumia 640, but there's no release date yet.
Should you purchase a Lumia 640 or Lumia 640 XL, you could be in with the chance to win a trip to Abu Dhabi and meet Lotus F1 Team star Romain Grosjean.
T-Mobile has confirmed that it has stopped selling its version of Microsoft's Lumia 640 on its website, just over two months after the carrier started selling the Windows Phone device.
