LOL ... before anyone breaks out the foil hats and climbs into the bunker, i think it's worth a proper explanation.
There is a process on the phone called "com.carrieriq.iqagent". This process allows an application to collect anonymous data on you which helps you in many ways.
Examples:
Menu > Settings > Location and security > click "use wireless network" and read the message.
Data is gathered and translated to help apps such as google maps. It can take your location data, translate it, and turn it into real time traffic reports on the map.
Another way this can be used is to target ad's in applications based on a persons location. Suppose you're in New York city, it does no good to show you adds for bakeries in San Francisco.
Also Google voice uses this service. I'm not sure how they use it but if i had to guess, I think you may need to be in the U.S. to use google voice (again thats a guess).
There are other apps and other reasons it's used but back to my point ..... Sprint doesn't care if you surf porn on your phone
Nobody is collecting phone, or person specific information. It's anonymous and used to improve you're experience on Android. If I'm not mistaken i believe apple has something very similar that was all the hubub not too long ago with the "ZOMG steve is gonna catch me looking at android phones on my fruit phone" crowd
