I'm getting other alerts (new mail, etc.) it's just SMS that doesn't play a sound. I've checked the volume level and it's set to the same as the phone ring level, which is fine.
Odd - I'm sure the same thing happened to me at work today. I got a text message which was marked as delivered several minutes eariler, but I didn't know I'd received it until I actually looked at the phone display. There was no notification sound played and I haven't installed any apps recently.
