Difference between Full HD and HD ready?

You're all very warm, but I haven't seen a completely correct answer. Yes, it's a mess.
HD Ready is an industry agreed standard. If you see this logo on a TV you can be guaranteed that it has at least 720 lines vertically, and at least 1 HDMI port.
As in, it is ready to show you HD, when you plug an HD source into it.
Full HD is just a marketing term, but has come to be accepted as simply, 1080p.
So in this case, as with many other TVs (but thankfully it's a problem that's going away now), you've bought a TV with a Full HD screen, 1080p, but with an SD tuner. That's fine really, as long as you know that's what you're doing. If you use a Sky box for example, you mightn't care about the internal tuner.
Following the 'HD Ready' definition above, your TV should have been described as 'Full HD Ready' as in you can have full HD, once you plug something suitable in.
If the description wasn't clear, and it almost definitely wasn't, take it back and punish the unclear advertising. It'll have been advertised as having 'Freeview' whereas you should have been looking for 'FreeviewHD'.
