Lots of rumors and changes ahead of the refresh of Apple's iOS lineup, expected to start with an announcement on September 12. Sprint has lowered the price of its iPhone 4S from $199 to $149 in anticipation of the launch of iPhone 5 — a move that's typical in advance of a new model in order to clear out inventory. In addition, iMore is reporting that the new, smaller, 19-pin dock connector expected on the iPhone 5 will also be rolled out to the entire iOS lineup at the same time: the iPod touch, the rumored iPad mini, the current iPad, and the iPod nano. In addition, the new version of the iPad with retina display with the smaller connector would, according to rumors, come with some other tweaks to reduce heat issues and improve performance.
Another interesting development is the news that the forthcoming iOS 6 will no longer come with a built-in YouTube app. 9To5Mac was the first to notice this, and according to Yahoo Tech news Apple then subsequently confirmed this was the case, saying that its contract with Google (which owns YouTube) had expired. This is just one more step in severing partnerships between the two companies, with Apple having announced it is dumping Google's Maps app in favor of its own.
You'll still be able to watch YouTube videos, either via Safari or via a YouTube app from Google that will eventually be available in the App Store.
