Might flash this one later to see if there is some AT&T specific tweak but I doubt it.
Based on the model number the GE radio is newer and this shows that AT&T is behind.. as expected.
The GE is Android 4.3 and the radio was no better than the international ones.
This 3250.20 radio along with the RIL files is the fastest my phone has ever been. a marked 5Mbps improvement at home and top speedtest scores of 40Mbps... I had never topped 22Mbps before this update.
Here's a link to just the firmware and/or radio if you don't want to run the full RUU >>>
And here's the Zip of just the radio and ril files flashable in recovery >> https://www.dropbox.com/sh/difkg48joxvf983/PXuojOTj6A/m7_att_radio_SENSE_4a-17-3250-20.zip
