Which phone company doesn't collect user information? When we had a landline, Southwestern Bell would send us a monthly bill showing all of the people we called long distance, when we called them and the duration of the call. I'm going to go out on a limb and guess they had all that data on local calls and didn't disclose it since they didn't bill for it.
Your cell phone company knows when and where you ping off any cell tower in the country / world.
We had a guy locally who was convicted because his car kept track of everywhere it was driven, speeds driven, when it was driven and sent to the manufacturer. The police used it to figure out where he buried his wife.
