1. The reference is found in a 2 year old version of iOS.
2. "IQAgent" sounds like things Apple could name, e.g.: I've seen no evidence that this has anything to do with CarrierIQ. There's been no disassembly (unless I missed it) so it quite possibly could simply be the fact that at one point Apple used the two letters "IQ" in an obscure file.
3. People watch the data iPhones transmit pretty closely, I know I have on occasion watched iOS devices talking to the cloud. If "every keystroke, every SMS" were being logged, I'd think people would have more than just a filename to go on.
4. As mentioned it seems this file is not used outside of diagnostic mode, which makes this much ado about nothing at this point.
I think its fine to be suspicious, but these things really should be approached with some objective detachment until actual transmission of user data that shouldn't happen is uncovered.
I don't know how many of the points above apply to the "indications" in android as well, but I think we should have more neutral, unemotional, and detached coverage of it as well.
I think spying on people is bad, and I think that americans are spied on more today than ever before. I think that's also why we have to be really careful about reporting it.
Edit: Deleted a digression that pointed out that the government is including language in recent legislation that allows them to collect data about us that previously would have been illegal. This was a distraction from my main point.
