Just had this happen to me for the first time today... it was weird. The text tone is a "3 part" for lack of a better term. It played the first 2 and then stopped. I thought "that's odd..." and pulled out my phone. Nothing on the screen. Hit the "wake" button (or home button, don't remember) and woke the phone to hear the very last part of the tone play (it had been 40 seconds) and my wifes txt flash up on my screen.Every now and then when receiving texts the notification stutters. Anyone else get this? It is the default text notification tone.

It's a bug with text tones, at work 6 of us have the 4s everyone has the swoosh noise can't remember name and when we get mail from our boss it stutters 3 times and sounds like 49 fighter jets launching torpedoes its really annoying
