MCTS Mobile Application
Last month Microsoft released new certification 07-540 for mobile applications for promotion M$ offered 700 free exams world wide (except Pakistan, India and China). I also get a chance to register my self and was a great experience for preparing the exam.
I am still waiting for the result but hopefully I will clear it … 
The track was mostly focus on Microsoft.net compact framework 2.0 and windows Mobile 5.0, really .net cf 2.0 is a cool framework and more importantly it is pretty similar with .net desktop framework.
More Information on 07-540 and .net cf can be found at
