Pretty sure bluetooth protocol itself is limited to one connection by design. So not a limitation of iPhone but the protocol.

Actually that is not quite true. Bluetooth is limited to one connection per device profile. That is to say you cannot have two bluetooth headsets actively connected at the same time, but you could have a bluetooth headset and a heart rate monitor, as the hrt monitor and the headset would be using different profiles.
