All night i've been trying to download the Android 2.2 update on my HTC Wildfire but it's not working. I've done everything as instructed and it seems to download it, turn itself off, then switch back on showing an installation screen. When it turns back on again, i get a screen saying "install system software update?" - Exactly the same screen as before i tried to download it, so i'm going round in circles and getting nowhere. What's wrong with it?? Thanks (before i throw it out the window)....
