Hey everyone, I updated to iOS5 last night and my iMessages won't activate. It says awaiting. Then it said it was unsuccessful. Then I rebooted the phone. Then I reset the network settings. Turned iMessages off and on. Still will not activate. Also when I try to get an SMS it says my mailbox is full. I have never had to delete any messages before. My friend with a 3GS isn't having any problems. Anyone able to tell me what is happening? Thanks.
