Apps? For a device that's been out just two months, there are currently 135 apps here, tested, stable and community approved.

And there's currently over a thousand in development in the garage.

For an OS so young, I'd say that's pretty good.

I'm not sure what's happening with GPS - though I believe sygic are bringing something paid in soon, and there are several apps in extras assisting location. As for MMS, fMMS is well under development. If you are willing to use something from 'extras-devel' you can be part of the testing. I don't think we have any MMS parameters for South Korea.

What else were you looking for?
