FreeType is also the font engine in the Symbian and RIM operating systems. I
know, because I put it there. And they are closed-source systems, although I
believe Symbian is moving to open-source. There is no licensing difficulty
as long as the use of FreeType is acknowledged.

With Freetype being GPL (x)or modified BSD licensed*, doesn't this
mean that either:

- under GPL license, the complete Freetype dependent software should be GPL
- under BSD license,  non of the other software may be GPL?

Does this mean that *if* Freetype is being used in iPhone, and the
sources are kept closed, the BSD license must thus apply, and thus non
of the dependent software may be GPL (due to the BSD/GPL license).

I am not interested in nitting about the iPhone, I just want to
understand how this applies to other semi-closed products who would
like to use Freetype?
