This began happening to me in the afternoon yesterday with everyone I iMessage and when they iMessage me back it plagues their phone in the exact same way with everyone they wish to iMessage. When I send the message it sends normally. Says Delivered for a split second. Then it jumps to Not Delivered. And then Read pops up after my recipient has read it. My Messages on my computer doesnt work at all (ML) and on the phone it works very weirdly. Ive tried resetting iMessage settings. Ive asked the people I've been texting to reset theirs. Ive restarted my computer. Nothing is working. I am running 5.1 Beta 3 and they are all running 5.0.1 normal. Has anyone experienced this? Anyone else having problems with their iMessage working correctly? I am on Fido in Canada. My other contacts are on Fido, Bell, Telus and Rogers so I dont think its a network thing especially since going on WiFi doesnt change a thing. Any help would be greatly appreciated.
