O2 in the press

If you look at this article

Why is your 3G coverage so appalling? Now that Orange and Vodafone, both of whom have better coverage, have the iPhone, will O2 be improving theirs?

And the response from Matthew Key:

Nikesh,
I accept that our network has been under pressure in parts of London, where we see the highest concentration of smartphone users. For two years we have been the exclusive provider of the Apple iPhone — the fastest selling and most powerful phone in the world. It’s been a steep learning curve for the industry and ourselves — the O2 network has seen an 18-fold increase in data carried over the network in the last year and traffic continues to double every three months. This level of throughput increase would cause pressure on any business. To put this into some context, watching an average YouTube video on a smartphone can be the network equivalent of sending 500,000 text messages.
We are constantly increasing the capacity of our networks and the good news is that we now better understand and know what fixes we need to put in place to improve our levels of service. Fortunately, it’s not about needing new mast sites and we are investing more than £30 million to address capacity issues in London alone between now and Christmas and I’m confident that we’ll see much improved levels of service as a result.

So hang on. They have a really good way of tracking how many customers they have. They sell the damn phones! If they dont invest in their network, keeping up with customer demand, what do they expect?

However, they do still keep the money, right ?
