So I lost my phone and I have been trying to use imessage on my mac and it doesn't seem to be working everything returns as not delivered. Help? THANKS
Have you tried Find My iPhone from your Mac's iCloud web login? Use it inform you when the phone is switched on\located & to put a message on the phone's screen, which would be more helpful than just sending a message, I would think - you can also lock it &\or remote wipe it ...once wiped you won't find it again though.
