Except for the specific addition of Band 30 on the AT&T model iPhones, it's the same device across carriers.

 

How is Apple able to do this while the other device makers aren't? Does Apple have a "don't mess with us" kind of leverage?

Samsung could easily flex it;s muscles to keep the carriers away from the software and device models like Apple does but I don't understand why not. At this point I'm sure no carrier wants to say no to carrying a Galaxy phone

Will this allow more reliability with calls and texts? What I mean is often I get texts late or calls won't even chine through although I'm next to a NV site. I'm wondering if this would help any.

Great question.The Galaxy S3 was "optimized" in that its highest EIRP was at Sprint's PCS G block LTE 1900 center frequency. The Note 2 was not; in fact, its LTE EIRP was worst in the PCS G block.So, take that for what you will...AJ

For reference with respect to ERP, here is how the 4G LTE compares to the original HTC Evo 4G:OG Evo 4G:

Channel 1013 (824.70 MHz): ERP=20.1 dBm, CDMAChannel 384 (836.52 MHz): ERP=20.3 dBm, CDMAChannel 777 (848.31 MHz): ERP=19.0 dBm, CDMA

Evo 4G LTE:

Channel 1013 (824.70 MHz): ERP=18.78 dBm H, 12.65 dBm V, CDMAChannel 384 (836.52 MHz): ERP=20.43 dBm H, 14.16 dBm V, CDMAChannel 777 (848.31 MHz): ERP=19.55 dBm H, 12.96 dBm V, CDMA
