I fail to see the need to use software serial library to get UNO and bluetooth to communicate. I don't think anybody else does. I only use bluetooth for data aquisition, but no extra software of any sort is required to do this.
I use SoftwareSerial so I can get 2 serial port: from arduino to pc with usb and the other one form arduino to BT module.
In that way, when I set BT module in command mode, I can send AT commands from pc to bt using arduino as proxy because I don't a FTDI cable.
