What I noticed is working:
*sound (maybe a bit laggy, don't know how the sounds suppose to sound like)
*can read SD card (found my photos)
*adb using Sony stock drivers and SDK tools
imports bluetooth and wifi pairings from android installation
*GPS (starts scanning at least)
*display brightness adjustment seems to fast, that it's almost flickering, switchin to fix brightness solves this.
*battery lasting short only (less than 24h)
*Wifi/GPS switched off after reboot (possibly also MBB)
* Camera (as expected), only the shoot button comes up, otherwise screen stays black
* battery keeps on showing 100%
* seems not possible to display time in 24h format
Louspeaker in a call can be enabled but no sound
I'd like to have some screen shots posted from the phone itself but the browser jumps where it shouldnt on touching i.e. the xda login fields...
