For US folks out there, I just noticed the pilot for BBC's Sherlock (the one hour version of A Study in Pink) is currently free in SD and HD in the US itunes store. It's kind of interesting to compare this version vs the originally aired 90 minute one and worth a watch if you've never seen it before.
No idea how long it will remain up and free, so snag it now if you're interested :)
