From sources that I have read it seems that new assistant for Apple, known as Siri is making owners use twice as much data then when they had an iPhone with no Siri. This obviously will put more of a pressure situation on Verizon Wireless which is the largest US carrier sold around 4.2 million 4th quarter phones. The interesting part is that if it is doubling your data, it would be interesting see how much money Verizon will make seeing that there is no more unlimited data packages. So it will be interesting see what data overages people will be seeing due to these types of data usage.
