I've a Samsung Galaxy S with 2.2 firmware. I'm using handcent instead of the default messaging application. In the default messaging app settings I have disabled notifications and disabled auto-retrieve. But when I get an SMS now, even after I had read it in handcent, I still get the new message notification overlay on the messaging icon on the homescreen until I click into it. Can i disable this, or better yet replace that icon with handcent?
What home screen application are you using? In Launcher Pro, I can long-press on the dock icon, and change the icon and/or shortcut. I can also disable the overlay from
Menu > Preferences > Dock Settings > Missed call count/Unread SMS count/Unread Gmail count
