I have a Samsung Focus with WP7 and want to connect to a bluetooth headset. I connected 2 different headset before and it will prompt me to enter the PIN (0000). But with the new one that I bought, the WP7 will find it, but it will automatically generate a random pins. So now it won't match with the pin of the headset. So how can I make my phone to allow me to enter the PIN. Thanks
