"A data-logging software company is seeking to squash an Android developer's critical research into its software that is secretly installed on millions of phones, but Trevor Eckhart is refusing to publicly apologize for his research and remove the company's training manuals from his website. Though the software is installed on millions of Android, Blackberry and Nokia phones, Carrier IQ was virtually unknown until the 25-year-old Eckhart analyzed its workings, recently revealing that the software secretly chronicles a user's phone experience, from its apps, battery life and texts. Some carriers prevent users who actually find the software from controlling what information is sent."
The EFF is hosting PDFs of CarrierIQ's C&D letter, as well as their response on Eckhart's behalf.
