zacharye writes "Bruised mobile carriers such as AT&T and Verizon are 'fighting back' against Apple's iPhone, despite the fact that the device has helped them eke out consistently higher average revenue per wireless subscribers since its launch. To hear the carriers tell it, the iPhone is a major inhibitor to their profits as last year they were 'only' generating wireless service profit margins in the 38% to 42% range. But ever since these beleaguered companies started 'fighting back' by implementing data caps, increasing fees for device upgrades and implementing longer waiting periods before users can switch devices, they’ve seen their wireless service profit margins surge. AT&T reported a 45% margin in Q2 2012 and Verizon reported a record-high 49% margin."
Thus mathematics may be defined as the subject in which we never know
what we are talking about, nor whether what we are saying is true.
