Cortana

So i got the 8.1 Update today and i was expecting cortana to take centre stage, but couldn't find it, until someone pointed out that you search for it using bing, but it says its not available in my region ( UK ) so can someone tell me when it is because ive been waiting for this and im hoping its going to stop me switching phones

It's only been released to UK developers at the moment. Still in beta apparently. You can register as a developer and download Cortana but this may invalidate your phone warranty.
