I don't think you can become a proficient C++ coder in one month unless you're really, really smart and unusual. Maybe not even then. Although, it depends on what you mean by "Hack basic apps", doesn't it? If you're working on existing apps then you'll need to know the same subset of the language that the original programmers knew. If you're going to write apps from scratch you might do very well by starting only with the Symbian programmers documentation, if it's good. Beyond that, just learn C and use C++ as a "Better C". If you can avoid using classes and templates you can start quicker.
