I would recommend to leave a message here about the user will see the both GSM and CDMA options in this panel. Since this is a bit confusing we would inform in that message that this is only for debugging purposes while developing CDMA support in B2G. I would also file a bug because we should change that at some point. I mean, once the development for CDMA support gets finished we should show only the GSM options by default.  Could you file a bug, leave a message and add the bug number to the message please?
