So, with iMessage it will send out a Text Message if it can't send it as an iMessage in 5 minutes. Is there a way to shorten the time that it waits? A friend of mine got iOS5 but for some reason doesn't want to do iMessage. So he turned his off and is just sending texts, however my phone still tries to send him iMessages. I'd like to get rid of the 5 minute delay for texts, but I don't want to turn my iMessage off for just one person. Any ideas?
