texting sky+ box

Apologies if this has been asked before but just did a quick search and couldn't see anything.

Just got sky+ and when i was on to sky ordering it, guy was giving me the whole sales pitch etc and he mentioned that the newer sky+ boxes have a feature where you can text your box if your out to set it to record something.
Looked through manual today and can't see that. Anyone know anything about it?

There is information on this on the sky site
