I bricked my first one as well. Black Lumia 920 from AT&T, was a pre order. Realized I was not getting a data connection unless I was connected to a Wireless Access Point. Figured a reset may help but it just got stuck on the gears screen. AT&T tech support had me hold down the volume (lower), camera, and power button. It then got stuck on the Nokia screen and nothing would get it out of that loop. Took it to a store for a replacement and data worked fine but the replacement had a defect in the Bluetooth, was cracking and popping noises over Bluetooth so I took that one back to the store for ANOTHER replacement. This one so far has worked near perfect, still nervous. The only thing I've found on this one is the camera flash won't shut off when taking pictures even though I have disabled it. Obviously something was rushed in order to get these devices out in people hands before the holidays. Hope they come up with a system update/resolution because this really is a beautiful phone with a great looking OS.
