It was originally planned for the end of 2014 so I don't know what happened.
There is some work going on in the area at the moment but there is no indication of the reason why and the roll out plans are not something that O2 are sharing with us unfortunately.
I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion.
