Does anyone know if the blackberry 8100 speaker is single plex or multi plex? I'm not talking about the speaker phone, I'm talking about the ear piece and mic. I called Tmobile and talked to the operator but she couldn't find out ethier.

I dont see why it wouldnt be full duplex. Especially in todays age... I dont see any type of phone being half duplex.
