Howard Dierking announced that the Mobile Exam has gone live [Via Email]:
The long-awaited mobility developer exam (70-540) was released today! Check out the preparation guide for a list of the topics covered and links to resources to help you prepare. When you feel ready, you can register for the exam at either Pearson VUE or Prometric.
According to Vue I passed the exam which I took back in September during the beta. That gives me another certification MCTS - Windows Mobile 5.0 Applictions. I think it is pretty interesting that even though I'm one of the first people to get the certification it is already out of date since Windows Mobile 6 has already been released.
