I wouldnt have thought there was much point unless you stay in a big city, i looked on my T Mobile account for coverage, and it wouldnt be worth it around my way at present
I’m in Leeds, so according to the ee coverage page, its here.
(The new EE service starts in 11 cities: London,Bristol, Birmingham, Cardiff, Edinburgh, Glasgow, Leeds, Liverpool, Manchester, Sheffield andSouthampton with 2,000 square miles of 4G network promised to be added every month).
I think its going to be in 70{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} of the uk by the end of 2013.
