Re: Incoming text message double alert sounds?
This was already suggested (first reply, actually). However, that's not the issue they are talking about. The issue in question is the tone going off twice rapidly, with the sound of the second alert often overlapping the first. If your phone is jailbroken and you have IntelliscreenX and Xmessages installed, this often can cause this issue. I've tweeted and emailed Intelliborn multiple times asking them when a fix will be available and never received any response from them (pretty poor customer service).
