applemasker writes "According to this story on Yahoo News via the L.A. Times, an upcoming cell phone directory which supposedly includes 75% of all cell users is in the works. Some people are already receiving cell phone spam and telemarketing calls. Worse yet, unless you opt-out at the beginning of your contract, some carriers such as T-Mobile can gladly hand over your info (though the article says that T-Mobile is changing the contract now). Some good news though, Verizon Wireless has said that it will not share its customer lists. Still, maybe it's time to submit your cell number to the Do Not Call List if you haven't done so already." We had a related story last year.
