Well it probably is some proxy / firewall thing, retested and it still doesn't work here. Not sure why the official client can connect though...

3g works fine now, though I had some problems with it on the road but that most likely is due to the moderate coverage here.

I do have one request. I think pressing pause also stops buffering. So far I have not had a problem with buffering but if the buffer runs out I would like to pause so it can fill up again.
