It seems like Verizon would only be able to use this information to improve the service. What company wants to know that I call a specific number from a specific location 3 times a week?
I find this similar to the Google apps, sure they could sell the info, but I don't see it being useful. Great they know I took a picture of toothpaste in the local store so i could compare the price online... and?
The most obvious collection of data I have seen is Amazon. Looks at what I look at and makes suggestions. I like it because I see more options!
For some reason I trust Google with my info way more than Verizon. Maybe because I don't have to make my the payment on two Droid plans to Google. Verizon gets enough from me already. I promised my secrets to Google <3
