Thanks Alistair, but I was being a bit ironic (or do I mean sardonic ?). A colleague in Norway had the first such phone that I'd ever seen, hugely impressed as it was almost as big as his little Volvo estate. One day I'll get a smartphone, until then I make do with an ancient phone that lets me call, receive incoming, and get the codes for Ebay etc. As you can tell I'm not really much into phones/texting etc.....
So was mine

except the bit about only useful thing they did was eat battery and play a game. Oh and make a shocking profit for Racal.
Was your colleagues phone a Mobira Cityman (the first device of a little company called Nokia)
I am guessing it was the same shape and size as his Volvo.
