My T-Mobile contract had been up for a few months but I was hanging on for a phone I wanted, unfortunately T-Mobile decided it wasn't worth having. Fortunately I had read about 3rd party upgrades on a forum somewhere, which I'd never heard of before. After a bit of investigation I had the numbers of a few companies, the Carphone Warehouse being the biggest and only one I recognised however the person I spoke to was unfriendly and unhelpful. After some research on some of the others I decided to call up Chitter Chatter. I spoke to a guy called Daniel who had a friendly telephone manner and was very helpful. He called me back after 20 minutes and we sorted out the formalities and a couple of days later my new phone arrived.
