i) I can produce a standalone 'executable'/installable file which is not open source, but dynamically links with qt libraries at runtime.
Correct. This was the biggest change to come about when Nokia bought Trolltech.

ii) The qt runtime libraries are already present on the maemo device/N900?
As I understand it, yes.

iii) Statically linking with qt libraries is not permitted if my code is closed source.
Strike that, I'm not sure. Statically linking isn't a good idea in any case, not sure how the LGPL falls there.

iv) I presumably cannot in anyway ship modified versions of the qt libraries.
Well, you could provided you made the source for the modified libraries available.

However, inheritance of the provided qt classes is permitted.
Correct.

Also, if possible, consider what Jed said
