Where do I find Unity iPhone?

Has it been integrated into the MacOS Unity? Because months ago I downloaded Unity iPhone 2.x and just a couple of days ago, I googled Unity iPhone, as I had done before, and downloaded Unity. I got a free license at first, but have since purchased the iPhone publishing license. Trouble is, unlike the version I downloaded months ago, this one is just called "Unity" (not "Unity iPhone"). And although I have replaced the free license online with the purchased one, this version still doesn't come with things like Unity Remote. And Build&Run (having been configured for iPhone/iPad publishing) doesn't publish to my iPad.
