Currently have a N4 running CM10.1.3. I'm very happy with the phone - and love having an unlocked device. This fall I've used sim cards in half a dozen countries without ever missing a step. I haven't minded the lack of LTE so much, but down the road I do want to upgrade to 4g/lte.
My question is, are there any devices out there selling with true international LTE support? By which I mean that the phone will work not only 3g when out of your home region, but fully in 4g (in any country with 4g coverage?) Is this a feature expected to be on new chipsets/antennas in the future? Ideally I want something very similar to the N4 insofar as it is not in any way region specific - but with LTE.
