When you say "it has the ability to monitor everything", do you mean that it would be entirely possible for Apple to build something into their phones to do this if they chose, or that they have already done it? The first one of those is clearly true - Apple has control over hardware and software and could put pretty much anything they wanted in there to track your activity. The second one is, to my knowledge, pure speculation. Apart from their anonymous stats - that you are able to opt out of - I've seen nothing to suggest that anything similar to this on iPhone.
