Are the Carrier IQ daemons installed on iOS devices other than iPhones?
I just did a quick check on my iPod4,1 running iOS 5.0.1. Those two binaries are not present in that folder. However, I have seen mentions of IQ in other parts of the system such as var/wireless/Library/Logs/awd (empty) and var/root/Library/Logs/awd (empty) and com.apple.iqagent.plist in var/mobile/Library/Preferences. The only value in that plist is DiagnosticsAllowed = false. I would conclude that Carrier IQ is not present on 4th Generation iPod Touches running iOS 5.0.1.
