I am new to the iPhone 4s and have a questions about how to silent a text ringtone when you receive multiple messages at once. Case would be if i receive one that is more characters than the 160 and gets split. I know if i receive just one i can click a button on the phone or swipe to silence it but it seems like if i receive 2-3 at the same time it will silence it then start up right as the next ones come and i am unable to silence that notification. I like to have a longer text ringtone, 20 sec, so i can be woken up by them or hear them better than a single tone in noisy places. Is there a way to do this or am I just out of luck.
