GiffGaff launching 4G on 12th November
I'm surprised there's no blog on this here at Mobot, or maybe I missed it.
Some customers were on the trial (similar to how Three launched), but that trial comes to an end on 11th November when the launch goes public on 12th.
Looking at the coverage map, it looks like it will be available pretty much everywhere that O2 already has the 4G coverage.
If you were an existing customer on or before 28th October then the Goodybags are slightly cheaper than for new customers for a limited period. The discount ends after 12th January 2015 though.

Looks like BT have delayed the roll-out of their mobile 4G until next year. I believe they are having problems mainly behind the technologfy that ensures seamless call handling when you move between an wifi access point and 3G/4G mobile coverage.
As I understand it, their superfast-mobile offering is going to be based on a mixture of 4G Mobile and Wifi Hotspot access
