That was my exact point to the Sprint rep, but he assured me it was doable... He had a Note 2 and claimed it would support the 800/1900 LTE bands through the same update method.... But not being versed in LTE technology I wasn't sure if it required separate LTE chips for different frequencies, or if the individual LTE chip could be programmed/updated to support multiple frequencies.. I know with some other forms of hardware, certain features come locked that can be unlocked through hacks and updates...
For example, the AMD Phenom II X3 was a triple-core CPU that through a hack, you could unlock a 4th core... There's plenty of other examples involving CPUs, video cards, etc, where the hardware came with certain specifications, but through hacks/updates, they were modified to enable additional features not originally listed.
Which is why I'm scratching my head over this... In the end, I won't doubt it for a second that Sprint pushed this knowing it would never support the 800mhz because they had a certain amount of stock to burn through, with Samsung planning to release an updated edition in the coming months with the curved screen and other capabilities...

It's not as if this information had not been floating about the web and XDA before the Sprint version was released. There have been several threads on this particular topic.
