1. Yes, there is a huge open source revolution on the server side, but not on the consumer desktop. My mom doesn't know or care if the web servers serving up pages are Linux or Windows. As a server-side developer, I've seen and been a part of the big shift to open source OSes, software, tools, etc... However, if you're talking about consumer desktop OSes and apps, there isn't one yet.
2. I haven't worked on an iPhone app. Not really my area. Sure Apple could be more open, although they obviously see reasons not to be, and that their right. However, I'd argue that they're generally more open than most of the widely used competition. You might wish the iPhone SDK supported multiple languages, but compare that to developing for the Motorola Razr, or the Blackberry? I think Apple is doing pretty well. Obviously not as well as some folks would like, but they're running a business and trying to ensure profits, quality, low support calls, all that stuff, and I respect that.
