We were talking about USB mass storage which comes built-in and your answer is out of bounds.
You can't do it via iOS either... I can pull files from my WP7 phone via USB, I can also do that and much more on the N9.
You can do it through HTTP as well. http://nokiagadgets.com/2012/02/22/n...eb-server-app/
Don't know what problem is with your bluetooth, but maybe it's hardware issue with your N9. Please contact your nearest Nokia center.
It's not Unity3D, it's only a toolkit for porting
and I doubt you know that XNA is not that functional as Unity3D is.
And I knew about it before.
I am here just to let the others to know the truth.
I am not saying N9 is bug free and have every possible imagined functionality. I know it lacks many things. But when comparing to WP7 crap it's clearly superior.
