I did that
still same thing, if I select the blank option in the usercp, and then click save, it tells me a flag is required.
what I did is slightly modify the code for the postbit, just deleting the "Country:" portion
doing that only shows the flag
so with the transparent flag image, nothing will show when the user selects "None" option, Like if nothing was there
I attached the transparent image for those interested (you will notice nothing is there lol, but is there..

)
1) add "None" to the country list (preferably at the top of the list)
2) add the image to the folder where you have the rest of the flag images
3) this will work best if you delete the "Country:" portion in the code
anyway, thanks again for the mod, members of my forum liked the idea
