Person 1: Hey, what is that in your hand?
Person 2: Oh, it's just a giffgaff— sorry, a riffurbished phone.

GiffGaffers 

Members of the “crowd sourced” mobile network provider who partly operate the network.
Customer support is largely provided by GiffGaffers, giving “Giff Gaff” customers. SIM cards are distributed partly through the good efforts of these “giving” customers. The network has a contract with O2 to provide its mobile phone network services.
The concepts of a “Mutual Giving” Mobile Network Service provider, enabled by the internet, and GiffGaffers, are similar to the concepts first documented in the Cluetrain Manifesto (Google it!) and more recently described by Doc Searles in his book “The Intention Economy: When Customers Take Charge”

(In response to the earlier definition, of course a phone with a Giff Gaff Sim should be configured for the Giff Gaff Sim)
(This is not to say there are no problems with GiffGaff, an example is the recent realisation that some excessively greedy GiffGaffers who “over-use” the low cost unlimited Data Sims are increasing the costs for normal GiffGaffers)

I am very happy with the support of GiffGaff’s GiffGaffers, so much so I have decided to become one!
