My BT connection is very reliable to my Pearl, using DM 4.5. But you likely have to use 4.7 w/your 9530.
If you can get a reliable connection, I think you'd be crazy to go back to the USB cable to sync (unless you leave your BB out all the time connected to a USB cable or something). I don't mind the mouse clicks, hated having to take my Pearl out of my pocket and hook it up to the cable, put it back, etc.
I know what you mean about the missing automated settings, though...it really is a bit stone age the way it is designed.
