>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.

The fact that those files contain a reference to http://collector.sky.carrieriq.com establishes a definite link to CarrierIQ, even if it doesn't actually run and send logs.
