If you live outside the US and are now running the dev preview of Windows Phone 8.1, you may well be weeping at the absence of one of its most important features: Cortana. But weep no longer, because you can get Cortana outside of the US, and it's incredibly easy to set up.
If you go into the settings of your device and change the region to US and then change the interface language to English (United States), you can get access to Cortana right now. Note that you may have to reboot your phone a couple of times but that’s a small inconvenience for getting access to the digital assistant.
As of right now, Cortana is locked to the US but it will be expanding it to the UK and China later this year, with further regions gaining support in 2015.
