I dont know if anybody is interested, but here is a working version of the Touchwiz4 Launcher that I can confirm works on the ns4g. I am using right now on MIUI. This is pulled from a rpm that I used to use on my epic. It is fully functional, no problems that I can find.
I did not develop this, I simply pulled it from a rom on my epic.
Credit goes to marcusant and whoever the original porter was.
