So I've been using my new iPhone 3G for a few days now, and I'm running into trouble. I've noticed that when someone texts me, my phone only vibrates. It fails to play the "Tri-tone" noise I selected. My phone is on ringer mode with the volume all the way up. I can confirm that all my settings are correct.
I tried using different ring noises as well as even restoring my iPhone. Still no dice.
A good few other people share my problem over at
Apple - Support - Discussions - Text message alert sounds disappear (3G) ...
Any suggestions? Anyone else have this issue? Please chime in. Text messaging is a big deal for any phone.
