Hi, i have update last time my PR 1.2 files , then i have found Problem.
If u have Bluetooth in use , then is the wlan connection go down, a listen of radio stream is no more posible. To see this problem , can u try to downlad any file with wget or check your wlan Router conection status. (iwconfig view no true output). I have try play mp3 from local device or Internet radiostream, in both :

BT on but Not in Use = ~700 Kb
BT on and in Use = ~20 Kb.

I have update my n900 to PR 1,3 , but nothing is change, same problem.

Any one can Confirm this Problem?
