"The answer isn't as simple as it may seem. Jailbreaking an
iPhone to work with competing cellular carriers cuts off an assumed
revenue stream; Apple and AT&T may not be happy with that. Even
the reality distortion field around Cupertino and the inexplicable
hatred for customers seemingly emanating from every national
cellular carrier in this country would notice if Apple sold a
million iPhones and only ten people signed up for AT&T's
service. Modding an XBox or an Apple TV sold primarily as a loss
leader to avoid subscription fees or network sales effects may cost
the vendor money."
