If you make most of your calls via cellphone, there's a good chance your call records aren't being provided to the National Security Agency -- if, that is, you're using Verizon Wireless or T-Mobile and most of your calls are between you and other cellphone users. Both companies say they haven't supplied data to the government, with T-Mob specifically stating that it was not involved "in any NSA program for warrant-less surveillance and acquisition of call records, and T-Mobile has not provided any such access to communications or customer records." If you're a Cingular or Sprint Nextel customer, well, it looks like you're in the same boat as the vast majority of landline users: those companies refused to deny participation in the NSA program.
