billinmtl I think you're right. I looked at it again, I haven't read much on it since a while ago. Apparently Google added encryption on top of the universal RCS profile which Apple says they will not adopt, rather they will work with GSMA to update the universal profile, presumably to add some kind of encryption. That may actually benefit us because, since Graphene doesn't use Googles RCS, Graphene to iPhone could be encrypted and Google would be left out
