Im slighlty confused, am i correct in thinking that the 3rd gen LTE is useless on major networks in the UK. However the new updated 4th gen is going to be more furture proof in terms of LTE connectivity? I soley bought a 3rd gen, based on LTE only to be told that it may not be compatible with UK carriers? If this is the case iv been mis-informed by apple when i purshased the device. Any help would be great.
