sorry it said this, i thought it meant it was for windows 10 phone...
For users of Windows 10 phones, Cortana gets improved functionality. Not only does it notify you when you have missed calls, but it also allows you to reply to those calls via SMS. For example, Cortana notifies you that John Doe called, you may simply voice-command it to "text John Doe," thus opening a text message. This feature uses your Windows Phone to send the text message.
Uber users also get more out of the Windows 10 update, too. Linking your Uber and Microsoft Account means that Cortana can now give driving direction to events, or even call you an Uber ride.
i thought that was what it meant it was on windows 10 but who cares i don't know why microsoft just worry about there operating system and let the phones to who know what they are doing...
but sorry for the misunderstanding...
