Its a few hundred bytes on average, that doesn't mean every phone reports every day nor does it take into account the number of phones with this installed whom rarely use the device. This probably lives on both my parents handsets and they make 4-5 calls and 1-2 text messages a week between them. I think that type of minimal usage is actually quite wide-spread which easily offsets higher usage users, and with presumably higher outbound data to CarrierIQ. An average across 145M users crossing various demographics and phones types is not a good metric to use to determine the possible danger of the data being sent.
