Cortana, Microsoft's answer to Siri, has been given a British accent for the jump over the pond, but is still considered to be in the beta testing stage in the UK. A beta phase is also rolling out to China, while Windows Phone users in Canada, India and Australia can opt-in to an alpha version.
With the snappily named Windows Phone 8.1 Update 1, users will also get the ability to stack live-tiles on the homescreen to make a folder much like the ones you'll find in other operating systems. When opened, the new folder tile will expand mid-stream in the homescreen, like a customisable homescreen of its own. When closed, its live-tile will cycle through data from all the apps it contains.
That isn't the only new feature in Windows Phone 8.1 Update 1, of course. Other little bonuses include a feature called App Corner — Kids Corner but for whatever apps you want — and customisable snooze durations (!) as well as support for future hardware features like dual SIM CDMA/GSM phones, and high voltage charging. No word on the 7-inch phone support though.
Microsoft hasn't set an exact date yet, but the updates will be rolling out "very soon." Start planning your folders now. [Windows Phone Blog]
