I had a question on how iMessage message routing works.
Assume this setup:
Apple ID: email@example.com
Apple ID: firstname.lastname@example.org
If Thing1 sends a new iMessage and selects Thing2's Cell as the destination, the iMessage appears only on Thing2's iPhone.
If Thing1 sends a new iMessage and selects Thing2's email address as the destination, then the iMessage appears on Thing2's iPad and iPhone (and at this point, there's two separate conversations from Thing1 on Thing2's iDevices).
I had assumed that since the Apple iMessage servers know that Thing2 can receive iMessages at both their iPhone and iPad (via their Apple ID) that it wouldn't matter if the iMessage was addressed to either cell or email (and that iMessage would route it to all associated devices).
Is that not correct?
