What, you thought the Microsoft news would end once the keynote from the Windows 10 Devices showcase did? Guess again because Redmond's latest operating system hits existing mobile phones starting in December -- the outfit said as much on its Lumia Facebook page. However, as Winbeta notes, it's going to be up to carriers to actually push the updates out to your handset. A way to sidestep that, of course, is by signing up for the Windows Insider preview program. Is your device going to get the update? That's a little iffy. First off, it needs at least 8GB of internal storage, and then it needs to be running Lumia Denim (system version 8.10.14219.341) to be eligible. So if you have a low-end Lumia you might be left wanting.
