I'm trying to disable incoming calls on my Hero using phone settings/call settings/call barring/all incoming. I am asked for a 'call barring password' but as far as I know, I have never set one nor does it say in the manual what the default is. I have tried the obvious ones like 1111 and 12345678 but I receive 'network or SIM card error' every time I try to enter a password. The password is 4-8 digits long. I am running Modaco Rom 3.1 on a T-Mobile G2 Touch. Can anyone help me on this?
