TwittARound is finished for weeks and ready for the App Store. Unfortunately it’s been rejected by Apple several times over minor UI misunderstandings. But the current submission should be accepted in the next days.
The App review process is getting better but it’s still a mess. A lot of other developers are complaining about it, too. In parts it’s necessary to guarantee working and stable applications. But in the end it slows innovation. It reminds me of the bureaucracy of a German Amtstube (office).
