My volume down button is playing up and as it is within the 2 year warranty I have decided to send it back to HTC repair [thanks SUroot for telling me about this]. One small snag is I am rooted and s-off. Rang HTC and they said that rooting does void my warranty but the HTC chap said I could go here www.htcdev.com, hit kernel source code and then see downloads and download the HTC Desire Android 2.3 upgrade and this would return it to a state that they would be happy with. This is what I did. It was easy enough to follow the instructions on the pdf file in the zip file and I was un-rooted in a matter of minutes. HTC were very good at emailing me instructions on what I must and mustn't send with the phone. I didn't have proof of purchase but that doesn't matter really. The only negative thing I would say is that they do not tell you to make a note of your serial number [under the battery when you remove it]. You need the serial number for tracking your device. Fortunately I had make a copy of mine. The HTC Repair centre phone number and opening hours are 08458900079 Mon - Fri 8:00 am - 6:00 pm (Mon - Fri) 9:00 am - 12 pm (Sat) The phone [less battery, sim card, sd card and back cover like the HTC chap said] was packaged up and UPS collected on Monday 12/9. I was able to track the package and it was returned to me on the Friday of the same week. It came back fixed. I honestly can't complain about my experience of the HTC Repair Centre. Thanks again to SUroot and Rastaman for their advice.
