Broadcom BlueTooth update for W2003SE ?

[Flow]

Hi all,

I have a Dutch HTC Blue Angel with Windows Mobile 2003SE and Broadcom BlueTooth.
The version is: "BlueTooth for Windows CE BT-PPC/PE Version 1.0.0 Build 3900"

Where can I find a upgrade/update for the BT-stack?
I need version 1.1 or 1.2 minimum.

Looks like there is a Bluetooth Profile update wich enables A2DP Stero Headset functionality, that works fine on 1.0.0 build 3900.
And there's a 1.6.0600 version being discussed in 2 topics and on the FTP, but that one doesn't seem to work if I may believe everyone who said so in those topics.

But now I'm wondering: Which BT version is this 1.0.0 build 3900 anyway?
Is it BlueTooth 1.1 ?
