Hi all, I'm trying to figure out which phones can tell that my messages were sent to a group and, if possible, reply to all or at least have the option of replying to all. This capability doesn't seem to fall under the MMS protocols (v1.2 and v1.3), but instead individual devices and carriers.

Do you have any idea which devices and carriers facilitate REAL group messaging, and if not, any ideas how I would track down the info without having to look up the specs of each individual phone?

Thanks in advance!
