I'm still not sure if these beta versions are open to the public or restricted to developers. I've never been a part of an open beta test since I depend on my systems for serious work. Even when I did registered beta testing of software and hardware, it was always done in a duplicate system so as not to interrupt my main operations.
I feel if your goal is to access beta software, just to be cool, or get an early jump on what is in the near future, then you are missing the whole point. Beta testing should be understood by all that it's use is to find where the product does NOT work. Then report it back to the sponsor of the beta testing. The goal here is to aid the developer in making a release that works flawlessly and offers new features. Beta testing also gives developers of 3rd party products a heads up so they can test their own products to determine what changes they may need to make as well. Beta testing, to my understanding has never been intended to be a tool for the marketing dept to promote the new release.
What I question is how Apple is distributing this iOS 7 beta. In all the post y2K beta tests of other programs, my registration had to be activated by the beta test division over the internet. It appears to me that Apple does not require this and the iOS7 is open to all who can download. In a way this appears to be a marketing plan in combination with beta.
Yes, Scott, I did find a reference similar to what you posted but also that each developer is authorized 200 UDID devices under his beta tester contract. Do I have that correct? Or, are you also just a sub under the real developer's contract? In my way of thinking, anyone the actual official beta tester authorizes to aid in the beta test program should report back to them and then they can choose to send those reports officially to Apple. A chain of command, so to speak. But of course, that would also depend on how the NDA is worded too. Considering the UDID authority, I don't see why Dishfan got scolded by the Apple store people unless he just got another one of their self proclaimed "Geniuses" who speaks with no brain attached to his mouth.
Not iOS-related, but if you have a "Safari" developer account - which is actually free (or was when I joined it), Safari 6.1 beta is out; and it includes changes to the bookmark bar. Seems pretty stable.
That is my guess. But other than with the changes in the side-panel for the bookmark button, I am not noticing much different; except it wanted permission to show a PDF in the browser.
