ZK. Do you think fixing the APNs like this may fix the 3g issue?
ddmclw, you can try my suggestion. I have a Verizon CDMA XT912 and have not had any trouble with MMS. I think I also have a stronger connection due to my modification. Basically, I have merged the stock APN's with that from CM11. It's hard to be absolutely certain that this is working as I think it is since the APN settings are locked out, but when I use this merged APN file on other ROM's, it always grabs my merged APN which is basically the APN settings as they were provided by Verizon so it should be the best settings.
First, boot into your stock ROM and see what APN you are connecting to. In particular, pay attention to the mcc and mnc. If your phone is like mine, the mcc is 311 and the mnc is 480. If your APN is different from mine, you'll have to manually merge your Stock APN's with the ones from CM11. However, if your APN is the same as mine, you can just grab my merged file.
Assuming your APN was the same as mine, you can follow these instructions to get the new APN's on your phone and working.
Grab my merged file: apns-conf.xml
Replace the APN file in CM11. It's located at: \system\etc\apns-conf.xml
Edit the build.prop file: \system\build.prop
Replace ro.cdma.home.operator.numeric=310004 with ro.cdma.home.operator.numeric=311480
You should now be able to dirty flash your modified ROM and reflash gapps, do the cache and davlik cache wipes, and hopefully your phone will reboot being able to send and receive MMS
