jetpack mobile theme rel=canonical?

Hi! It does not:

But you can customize the theme to do that; check out the last section here:

https://jetpack.me/2013/06/27/customize-mobile-theme/

https://github.com/Automattic/Jetpack/blob/master/modules%2Fminileven%2Ftheme%2Fpub%2Fminileven%2Fheader.php

Or, if you think that this is something that should be included by default, you canopen up an issue for it here:

https://github.com/Automattic/jetpack/issues/new

Let me know if you do that!
