Sneaky AT&T. My wife upgraded her phone this past weekend and they added "device protection" for $17/month without asking or confirming. It also didn't appear in the body of receipt emails sent afterward. You could only find it by clicking through a generic "what you ordered: wireless" email, being directed to a sign-in info page (huh?), knowing enough to find the order status page, and then finding the still in progress (again, huh?) order. Even then, it didn't show up as a change. It's just kinda there under the phone.
