Where are you, which country, as of just now Cortana is not available in the UK, but Windows 8.1 is available on all phones running Windows 8, though the release is down to your phone provider, but any of the new phones, 530, 630, 730, 830, etc will come with Windows 8.1 but if in the UK not Cortana without a bit of work.
