All I've uncovered what could be a serious problem with the Desire. It's only affected me in one way so far, but who knows what other problems there are that I haven't found. I've noticed on several occasions that when listening to music via Bluetooth, my headphones disconnect for no apparent reason. However I've found a pattern now: if WiFi is turned on and I come within range of a /remembered/ hotspot, the WiFi connects and BOOM, disconnected from audio. I can reconnect straight away. There is another poster here (sorry, can't remember your name or the thread you posted in) describing another problem with WiFi and Bluetooth working - or conflicting! - together so I don't think I'm the only person suffering. Who else can reproduce it and how could I submit a bug report to HTC?
