Hi all, I'm new here and have just got my HTC Desire. I switched the phone on for the first time and it's stuck on a screen with a green icon on. The icon is a down arrow with two arrows going around in a circle. What am I supposed to do here? I've pressed on the screen and held for a few seconds, pressed and held each of the buttons and no response. Not even the power button works. Any ideas? Many thanks in advance for your help!
