Bug 1098609 - Always display the menu based on the supported network type of the sim slot

https://bugzilla.mozilla.org/show_bug.cgi?id=1098609
This is the fallback when there is no data connection. If the modem supports both gsm and cdma, it shows the UI for gsm by default. The idea is that currently the UI for cdma only contains roaming preference and it does not help users re-connect to the network. Showing the UI for gsm allows users select other operators and get connected again. WDYT?
