My apologies if that has been mentioned already but I check every so often Now Broadband website www.mynow.co.uk
and was surprised to see that they're offering 4G now in Reading and Southwark. I'm hoping that within next September when my O2 contract is up that they will reach Shepherds Bush (this exchange has a FTTC Date of December 2013). 40MB AND 5MB upload will suit me fine. I remember trying their services 5 years ago and then they stopped offering it in London. I gues they were biding their time.
