The Chicago Police Department is warning officers their cell phone records are available to anyone — for a price. Dozens of online services are selling lists of cell phone calls, raising security concerns among law enforcement and privacy experts….

How well do the services work? The Chicago Sun-Times paid $110 to Locatecell.com to purchase a one-month record of calls for this reporter’s company cell phone. It was as simple as e-mailing the telephone number to the service along with a credit card number. The request was made Friday after the service was closed for the New Year’s holiday.

On Tuesday, when it reopened, Locatecell.com e-mailed a list of 78 telephone numbers this reporter called on his cell phone between Nov. 19 and Dec. 17. The list included calls to law enforcement sources, story subjects and other Sun-Times reporters and editors.
