Pardon my (now-out-of-date) iPhone’s measly 5 mega-pixel camera for the blurry image.
This is an HTC Surround running Windows Phone 7 during the Mango update.
The picture shows a phone connected to a computer with an arrow above that’s crossed out. After speculation, I realize what the designer is trying to tell me: “DON’T UNPLUG YOUR DEVICE”
I don’t know if it works, but I appreciate the use of RED as a warning sign.
