iMeet application is ready. I am very proud of this application, as it represents my achievements in fast learning and adapting to: new way of programming, as XCode and Interface Builder truly represent the ModelViewController paradigm; new language- Objective-C, which as any language has its pluses and minuses; new device: mobile devices on which I didn’t work since my experience on Sales Force Automation in TotalSoft company, back in 2005, on Windows CE.

Mostly, I believe that comes from the struggle of Apple guys to assure the stability of the system. A lot of errors can come from poorly designed overloads, thus the crashes can appear.
