I've been also having problems with at&t for the last 72 hours. I live in the northwest. I don't have any internet connection or iMessage indoors anywhere I have to go outside... Never have had this problem before. It must be a network issue of some sort or solar flares lol
Think its an AT&T problem, I am currently using a GS3, I wasn't getting texts for a while.... then like 10 all came at exactly the same time, one of which was a picture I sent from my work phone to my personal phone, which took 2 hours.
I upgraded to ios 6 about 4 days ago and I'm suddenly having issues with iMessage. It started this morning with not getting text alerts from iMessages and even some regular text messages. So I decided to turn off iMessage and then turn it back on and now iMessage is "waiting for activation". What can I do? I've tried rebooting, resetting network settings, changing time zone. I have the white 4S on AT&T. Anyone else experiencing similar issues?
