Looking for a super-cheap Windows Phone that can be updated to Windows 10 Mobile? Then you should check out the latest Best Buy sale as they have cut the price of AT&T's no-contract version of the Lumia 640 in half, from $59.99 to just $29.99.
This is about as cheap as we have seen for a new Lumia 640 unit, and if you join the Windows Insider program you can download the preview version of Windows 10 Mobile on the device. The 5-inch smartphone has a 1280x720 display, a Qualcomm Snapdragon 400 processor running at 1.2GHz, 1GB of RAM, 8GB of storage, with a microSD slot, a 8MP rear camera and a 1MP front-facing camera.
