Interesting stuff – 4G could be a competitor to BT landlines. Latest news from 3:

Three will be one of four main providers when it brings out the latest mobile internet for smartphones this summer.

Rival firm EE already offers 4G and charges around £5 a month more than for 3G on its Orange and T-Mobile brands.
The new LTE technology, more commonly known as 4G, will allow much quicker download speeds than 3G, meaning that smartphone users will be able to watch videos on the move.
Many other countries already offer the faster network and most providers charge around 20 per cent more for it.
Dave Dyson, the CEO of Three UK, said: “As we add the next wave of technology to our Ultrafast network, we’ve listened to our customers and thought long and hard about the right way to do it. We don’t want to limit Ultrafast services to a select few based on a premium price and we’ve decided our customers will get this service as standard.”
