I don't know how many people out there use iblacklist. I like to use it to prevent text messages from just popping up on the screen. Works great for that. What I discovered is when iblacklist is enabled the incoming text sound isnt as loud. Seems like it turns the sound down even though the volume is all the way up. I have noticed is sounds much lower. Also if you use the the Vibra app (Makes iphone vibrate 3x instead of once) it will not vibrate either when iblacklist is enabled. Anyone else notice this? When I turned iblacklist off everything returned back to normal.
