Verizon, Nokia and Research in Motion issued categorical denials to Computerworld that their products include Carrier IQ software.
"Reports about Verizon using Carrier IQ are false, Verizon spokeswoman Debi Lewis said via email. "Verizon Wireless does not add Carrier IQ to our phones, and the reports we have seen about Verizon using Carrier IQ are false," she said.
In a similar statement, RIM denied that it installed the software on its BlackBerry devices. "RIM does not pre-install the CarrierIQ app on BlackBerry smartphones or authorize its carrier partners to install the CarrierIQ app before sales or distribution," the company said in a statement. "RIM also did not develop or commission the development of the CarrierIQ application, and has no involvement in the testing, promotion, or distribution of the app," the statement said.
Nokia spokesman Keith Novak also denied that the handset maker integrates the software into its handsets and said that reports suggesting the contrary are incorrect.
In a statement, Android maker HTC said that Carrier IQ is required on its devices by a "number of U.S. carriers." The company did not say whether the carriers are asking for the software to be integrated into both its Android and its Windows Phone OS devices.
"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," the company said. The statement added that HTC is looking at ways to give consumers a way to opt-out of data collection by the Carrier IQ application.
A Samsung spokeswoman said the company integrates Carrier IQ into its products at the request of carriers. It did not specify which of its handsets carries the software.
