EE have applied to ofcom to have their 1800Mhz spectrum refarmed for 4G useage.

Perhaps the UK LTE rollout wont be as delayed as first thought?

If Ofcom approves this (and I don't see why they wouldn't) then I could see EE potentially shunning the 4G auctions completely and going with a full 1800Mhz rollout.

Although I would expect they might have some trouble sourcing phones that will run on 1800Mhz LTE - I don't think any other country will be using this frequency for LTE, will they?
