Regarding the Radio Chip in the iPhone 5, apparently it is the WTR1605L Qualcomm chip which supports a total of 7 frequency bands: three below 1GHz, three above, and one ultra-high 2.5 GHz+ frequency.
So if this is the case shouldn't the UK iPhone be able to support both the 800Mhz & 2600Mhz LTE spectrums as well as the advertised 850Mhz, 1800Mhz & 2100Mhz frequencies?
Is it possible they have only listed the 850Mhz, 1800Mhz & 2100Mhz because they are the only ones currently in use and once the others are actually operational they will just update the compatibility specifications?
