Hey Everyone, There is one contact in which my iMessage will sporadically "die" and will fail to send as an iMessage. Whether I'm on WiFi, LTE or 3G (even with 3+ bars of WiFi), the message bar at the top after I click send will zoom past and then the message will stay blue for about 5 minutes, after which I check back and it ended up going through as an SMS. I have tried resetting all network settings, resetting all settings, and even restoring my iPhone as a new iPhone. None of these worked. I have also turned On/Off iMessage, WiFi, and Airplane mode. These are all temporary solutions. I made sure that in my iMessage settings only my number is selected as a send/receive option, and completely turned off iMessage on my computer (Mac OS X Lion). I did not have these issues running iOS 6 (betas) on my iPhone 4S. Have you guys faced any similar problems? Come up with any solutions?
