Namespace requirement needs to be more obvious

The requirement to use "QTM_USE_NAMESPACE" or "using namespace QtMobility" is linked on the front page, but at the bottom and it's not always obvious what happens if you don't do it (e.g. #include "qversitreader.h", compiler error about unknown identifier 'QVersitReader' - huh?).

Perhaps it should be mentioned prominently in each API overview's landing page?
