I currently use Handcent SMS to control my text messaging. I used to have a G1 but got it replaced with a MyTouch Slide. On my G1, there was an option in the settings that allowed me to disable notifications from the system's original messaging app. However, I want to disable it since I get a notification from Handcent SMS and the original app. Both ringtones go off and there's 2 notifications at the top.
