I tried that wiki sample code (just some serial outputs modified) believing pins 1 and 2 should be the right ones (after trying unmodified sample code with pins 11/12 -> not working):
Did you mean pins 0 and 1?
If so, your code doesn't reflect that. And, you can't do SoftwareSerial on the hardware serial pins. Especially while still trying to do hardware serial on them.
A link to the shield you are using would be useful. If the manufacturer supplies sample code that says that the bluetooth device is connected to some pins, I think I'd accept the fact that the device IS connected to those pins.
