I must say that Microsoft's support is quite amazing. My original Lumia rebooted and got stuck wiping yesterday morning but would never finish. I took it to the Microsoft store at Tyson's Corner mall (despite buying it from AT&T directly) that afternoon, explained the situation, and they replaced it with a new (not refurb) device no questions asked. The replacement had the infamous light leak, so I took that one back this morning, and they replaced it as well, even changing to a black one at my request.
