The spectra used for LTE by Apple are currently consumed by SD-TV (700Mhz) or 3G (2100MHz) and not scheduled to be handed back for another 1-3 years which is why local carriers have had to use 1800MHz for LTE which is less popular (but hardly unique) than those other 2 spectra. Still, our 3G peaks at around 21Mbps which is good enough for virtually any use so it isn't a big deal. Apple chooses not to support 1800MHz since it is less popular than the other frequencies and they don't tend to localise devices.
