1) I figured out why yours shows WCDMA
Depending which Band you do last that is the one that shows from step "9) Press menu and back and select [2] BAND SELECTION"
so If I do WCDMA last that is the one that shows...
If I do GSM last GSM will show..
Regardless I just change it to UTMS GSM..
Not sure what WCDMA is .. I thought CDMA is only in USA
2) I used this APN and your HiAPN solution together

I did that and then HiAPN asked to overwrite I chose to keep it.
3) the roaming
- Roaming network (select roaming network) is grayed out
- Roaming setting are all grayed out but GSM -Data (checked it)
-Roaming gaurd - all grayed out but GSM ( I unchecked it)
that must be the norm I tried it on 3 phones, so I am not worried.
4) How can I stop the automatic MJA software download. nagging at me..
Disable OTA updates for L720 ?
I am using a Not activated Tmobile Sim to test it.
It find AT&T and Tmobile Networks when I search , connects to tmobile and shows HSPA .
Thank you very much for this AWESOME post!
Now lets see if anyone had the courage and upgrade the baseband to MF9 after and see if that effects anything..
and lets find a way to avoid that OTA nag for MJA
