This is a great step in the other direction. I'm hoping that once the noise dies down, we'll start seeing more of the good kind of serious iPhone apps.
Of particular note is TTPhotoViewController which emulates Apple's photo viewer, and which consequently is not available to developers via the SDK. This will save a lot of time.
I am not sure how useful the others are. For instance SDK 3.0 includes a new messaging UI similar to what TTMessageController is trying to achieve.
Also TTNavigationCenter seems a bit iffy. Using URLs to manage instances of UINavigationControllers. The iPhone is a different paradigm than the web so I'm not sure how effective mapping the web's main navigational structure to a less dynamic environment will fare.
Still, I am very excited about TTPhotoViewController. Thanks Joe!
