Last week, O2 UK released a ROM update for their Xda IIs Pocket PC Phone Edition (aka HTC Blue Angel) Version 1.31.139 is available for you to download now and fixes/changes the following items: an on-screen button to quickly flick between Landscape and Portrait modes fro O2 Active User Interface, repositioning of the O2 icon, (finally) Bluetooth build 3500 - featuring improved pairing, compatibility and operation and last but not least general operational updates, improving power management and device stability.
The ROM update is available from O2 UK's Xda micro site. Please keep in mind: this ROM was designed to work with O2 UK's version of the HTC Blue Angel only! The ROM update deletes all files from your Xda IIs so better synchronize before you update but don't use backup/restore since some system files might be changed as well.
