Conclusion: Yes it does. Outsite US the TV also supports Netflix (8$ monthly) and Pandora (free) if you subscribe to http://www.unblock-us.com 5$ monthly - free one week trail.
I now have the Sony KDL40EX503 and it works great with Netflix and Pandora from my location in nothern Europe (Normaly these services is blocked here; but UnblockUs does the trick.)
It is easy to setup the Sony TV. You recive some codes and connect the TV to your Netflix and Pandora account.
Netflix picture quality is good. My internetspeed is 8.8 Mbit. The Netflix user interface is good. Buffer time: From I press Play on the remote to the movie is playing : 45 seconds. The picture will get better/sharper after playing the movie for 2 minutes. (See attached picture)
The Pandora user interface is a bit under average, compared to other well known Pandora apps, like the one on iPhone - but it works 100 %. (See attached pictures)
So if you got a Sony TV that supports Netflix and Pandora (it does if it has Bravia Internet Video) and your are located outsite the US, I recomment you to try out UnblockUs.
I have setup my router to use the UnblockUs service; so any device I connect to my homes Wi-Fi network will access Netflix, Pandora, Hulu, BBC iPlayer ect. with out any setup on these deviced. It just works ! And it is easy to setup your router, see this page : http://www.unblock-us.com/how-to-set-up/
