Launch, then, is imminent. We never did get a hard launch date for Windows Phone 8.1, but most estimates put the roll out towards the very end of June. And here we are with signs that the mobile OS is about to go live.
And although a mass rollout is yet to kick off, things are starting to move in this direction.
The newest hint for this is the fact that Microsoft have recently listed Windows Phone 8.1 on the update history page right here, along with a rundown of features that users will get once they upgrade their smartphones to the newest version of the mobile operating system.
There are four variants of Windows Phone 8.1, namely 8.10.12359.845, 8.10.12382.878, 8.10.12393.890, and 8.10.12397.895.
Which version you get depends upon your carrier and country, but you will receive one of these four.
Redmond has also confirmed that the update will come with Cortana, the digital voice assistant, though this feature will only be available in the United States right now. Sure, there is a workaround to enable it for other markets, and you can read all about that here.
Anyway, the other major improvements in Windows Phone 8.1 are support for dual SIM handsets, more columns on the Start Screen, separate volume controls, an option to install apps on SD cards, and automatic app updates.
