I have this issue all the time but I can never remember how to fix it. I did a wipe and installed the latest sapphire ROM and installed handcent. I'm getting double notifications even though notifications are turned off on the default text message app. I even uninstalled handcent, and I still get a buzz + ringtone when I get a text from the default messaging app even though notifications are OFF. I even enabled them, set the ring to silent, and turned off vibrate and then disabled them again and I STILL get a buzz + default ringtone for every text received. Can someone please tell me how to fix this? My phone buzzes a total of 4 times and has 2 different ringtones for every text I get, and I get a LOT.
