I just picked one of these that I intend to keep as a spare WP8 device. My 928 will still be my permanent device, but I just needed one with all of AT&T's apps. I paid $79.99 for one of these for a colored back and a free 8GB microSD along with a USB nub and a charger (sans usb-adapter) from a local RadioShack. Nothing has really been unpackaged, but I'm still drudging through. I just took a few screenshots, but more soon. The first thing I'm testing will be the dial codes WITHOUT updates.
