This may be a reference to the fact that on upgrade, people dont tend to get as good a deal on the handset as they would if they were a new customer. In fact, unless you are on a higher tariff, or are particularly good at dealing with the network and haggling, then you may find that the only handsets free on an upgrade are those that are either lower in spec or older than the phone you have currently! Could be considered a downgrade I would say! The latest and most highly specced phones are rarely free on upgrade unless you spend a lot of money with the network.
