The Apple statement, as reported by AllThingsD read:

We stopped supporting Carrier IQ with iOS 5 in most of our products and will remove it completely in a future software update. With any diagnostic data sent to Apple, customers must actively opt-in to share this information, and if they do, the data is sent in an anonymous and encrypted form and does not include any personal information. We never recorded keystrokes, messages or any other personal information for diagnostic data and have no plans to ever do so.

Apple's admission, which leaves open the possibility that earlier iDevices still contain Carrier IQ, contrasted with blanket denials from Verizon, Nokia, and Research in Motion, all of which were named by Trevor Eckhart as providing devices that had the software installed.

Carrier IQ, the new poster child for (alleged) smartphone privacy violations, has been hit with two class-action lawsuits from users worried about how the company's software tracks their smartphone activity. Carrier IQ, of course, professes its innocence. But the company has also received some public support from security researchers who say Carrier IQ's software is only tracking diagnostic information and likely is not violating user privacy.
