Those who bring sunshine into the lives of others cannot keep it from themselves. ~ JM Barrie
Carphone Warehouse (Hitchin) confirmed what I suspected - the Samsung Salaxy Nexus is not available for ordering at the moment. I'm still waiting for the refund from PurelyGadgets (Tesco Direct website says the Nexus is in stock but I don't believe it) .
However, I have a new Samsung Galaxy SII phone thanks to MWNN and 'The Boy Raymond' at Carphone Warehouse (Hitchin) who did me a very good deal as an 'upgrade' using my existing Vodaphone PAYG SIM.
