Contacted HTC and HTC Netherlands through Twitter.

HT23 here by the way... Problems started after about 3-4 weeks of use. I'm hesitating to open up the device, soldering is not one of my strong suits. But sending it back for repair doesn't guarantee results either, as wph showed
But my Bluetooth and Wifi are pretty much useless atm, and I have a great Sony MW600 headset I use a lot...
So for now I can only hope the fix it or exchange it for a new phone that is working properly. I wrote the link to this topic on the repair form, so hopefully they visit this thread and watch the movies. But I'm not sure about that, because the first time, I attached a letter explaining the problem and photo's of my HTC Desire next to my One X with WiFi Analyzer open, where the difference in signal strength was very significant. But they sent it back unrepaired anyway. For now I can only wait and I will keep you informed about the results.
