We look at the code in gaia-apps-settings-carrier.js,from the API:mozMobileConnections,we can get the networkInfo,but it just contain:longname,shortname,mcc,mnc,rilMessageClientId,cell,gsmLocationAreaCode,gsmCellId,type,signalStrength,relSignalStrength,state.Have not the network type like 2G or 3G.
Please confirm whether or not include this field,thanks!

This is an always recurrence bug,this log may have not much help to solve the problem.
I hope to know if there is a API,from it I can get the network type for 2G or 3G,thanks!

Yes, here it is:

http://dxr.mozilla.org/mozilla-central/source/dom/webidl/MozMobileConnectionInfo.webidl?from=MozMobileConnectionInfo.webidl#49

And possible values:
http://dxr.mozilla.org/mozilla-central/source/dom/webidl/MozMobileConnectionInfo.webidl?from=MozMobileConnectionInfo.webidl#6

According to the values, you should be able to know if it's 2G or 3G.

Oh, I seem misunderstand your questions.
The issue is talking about when user manual scan network operators in the area, user has no way to know the operator type.

Hmmm, when gaia queries mobielConnection.getNetworks() the return result is the array of mobileNetworkInfo. And now, mozMobileNetworkInfo doesn't provide 'type' attribute [1].

This is a dup of bug 997071. I guess this bug had more info here.

The return value is determined according to ril.h [1].
There's no information about the network type. Gecko provides what we could get from rild/modem.

Please see comment 8 and bug 997071 comment 3. I believe this is a customization issue. We won't and have no way to resolve this in reference phone.
