I have the iPhone 4 and today when I went to go send an iMessage at first it said delivered and then when I went to go look at it a couple minutes later it had cleared all my messages before that one but only had the message I just sent on there. Then I ignored it and looked again a couple of minutes later and it was being slow and all of a sudden all my old messages appeared back up and the one that I had just sent was gone? Can anyone tell me what happened or what went wrong? Did the message actually send or no??
