An EFF volunteer – Jered Wierzbicki – has created an application called IQIQ to decode Carrier IQ profiles back to XML. Their public git repo is in the linked article. In a nutshell, Profiles contain what data is sent back at what interval and to where.
We are now able to see sets of metrics sent from phones. The problem is right now we only have default profiles. The EFF is looking to collect as many profiles from as many different devices as possible trying to find real metrics being “sent home”.
I have started a thread over at XDA explaining what the EFF is looking for if you are looking for instructions -
Please try to help them out any way possible!
