Apple, HTC, and Samsung said the software was installed on their phones. Apple said it had quit supporting the application in iOS 5. It said, "With any diagnostic data sent to Apple, customers must actively opt-in to share this information ... We never recorded keystrokes, messages or any other personal information for diagnostic data and have no plans to ever do so." It said it would scrub the software from phones in some future release. HTC (whose Android phone was the subject of Eckhart's video) said, it was required on its devices by a "number of U.S. carriers." It added "It is important to note that HTC is not a customer or partner of Carrier IQ and does not receive data from the application, the company, or carriers that partner with Carrier IQ."
