this new update will bring sth everyone love :D go go SONY . i love ur brand name .
Looks like it's got one serious bug though. Earlier today while I was at work, it couldn't stream any sound to my SBH20 even though it's connected (even the controls work. But no sound.) And right now I just got home and tried pairing it with my SRS-BTM8 - successfully connected, but no sound either!
It seems that Sony are not satisfied by the screen and the camera quality like a lot of us and they are working on them and trying to improve the stunning Xperia Z...great job Sony ;)
