In the USA they've gone LTE with smartphones first. The chances are more than likely that manufacturers will want to offload their production runs in the UK as well.

That said, I do expect to see Dongle, MiFi and 'Cube devices very rapidly, if not at launch.

But the reality is that LTE will be for the year 2013. This year, at best, we will see the emerging networks with all of the same problems that we saw with 3G when it launched.
