Might be my impression but the i9250 performs a little better catching H signal, I just tried for 1 day.
I'm not completely sure about this, but I think that little piece of metal is present on the Japanese model as well, but covered up. I think it's odd for a nexus device to have hardware variations that affect performance.... let alone the docomo simlock itself
simlock doesn't affect performance. It's a software setting, not something running constantly in the background.
That "small antenna", as has been mentioned a few times is an SMA Connector. It's not an antenna, but an antenna port. And yes, you are correct (and you can even see in his photo) there is a small plastic sticky over the docomo's SMA connector.
My suspicion is his two phones are on different basebands
. Baseband can make a big difference in your phone's ability to connect on H reliably and quickly.
Alternatively, if they're both on the same baseband, it's quite likely just a matter of perception. He only had it for a day when he commented and I'm not going to worry myself unconfirmed anecdotes.
