I haven't looked for the thread where I was discussing it last, my experience though was that I couldn't figure out how to get go sms to blacklist the texts. I didn't want to go back to handcent with it. I think I could have done it with that.
Also, there was a gapps file that had vvm in it, when I flashed it though, I lost voice search.
You need MB to address this for you. Actually, in the Have you tried aosp or cm7? thread, I think he went through all of the problems and workarounds he had found for them. I know I read where he did somewhere though.
That would probably help you, see if i can find it for you.
edit: Nope, not there, still lookiing...
