This includes things like returning the last call, or selective blocking of particular callers. For example, on my at&t landline, you can tell it to call back the last caller, or add it to your block list, even if you don't know the number since it was CID blocked. Obviously, if a feature is being done by an application on the phone, this doesn't help, but it works fine when done by the network.
Years ago, cellular networks were second-class citizens in the phone network (they connected sort of like big PBX systems rather than phone company peers), so certain features were not available, but now they are just as capable as any landline provider. So there is really no excuse for them to not offer any feature that you can get on your landline phone, such as blocking calls that are "private" (CID blocked).
For the same reason, the comment on the VZW Web site about In-Network being available on incoming calls only if the caller does not block CID is meaningless. I have plenty of calls on my bills which are marked "IN" and "<private>".
