Default How to improve radio performance?
Been quite pleased with my Jade so far. It's what the Diamond should have been.

The disappointment came when I got to work and I couldn't get a 3G signal. Even the Diamond could get that!

I have stock HTC ROM 1.40.721.2
Radio 0.27.30.9


Is there a specific radio version that will work better in the UK?

Any ideas of how to improve the performance or am I just going to have to bin yet another windows mobile device?
