Im not sure if this was supposed to come with the Iphone4s but when I get a text from somebody and I have it to a 30 second ringtone generally when my pop up alert comes on and it gives me an option to reply or close I assume the ringtone stops playing, but even when i close or reply to the text it keeps on going! Its driving me nuts especially if I want it to stop when I've made a gesture to what to do with my alert. Does anybody else have this issue or can this be fixed.?
