First off, the title, once more, has absolutely nothing to do with the actual episode, aside from a brief mention. Moffat's done this before ("Let's Kill Hitler", anyone?!), and it's kind of annoying. I like subtle titles that don't just give a description of the threat, but it should have something to do with the plot.
Drive-by posting to defend the "Let's Kill Hitler" title.
There's some strong parallels inherent there. The Teselecta stopped their assassination of Hitler because they realized it was too soon - you can't kill Hitler before WWII because it would be changing time. That's one of the basic precepts of time travel. Likewise they knew that River couldn't kill the Doctor here because he dies in Utah in 2011. Likewise we
knew they couldn't kill River here because we already know when she dies - in the Library.
So the "Let's Kill Hitler" title was actually an encapsulation of that entire aspect of time travel.
But I will grant you that "The Bells of St John" is a lot harder to explain. All I can come up with is that the Tardis phone is what called him back to action from his self-imposed exile which started the whole storyline off, but I'm not sure that's worth naming the whole episode after. Ah well. It's something else for us to spend pages and pages speculating over, if nothing else.
