Hi Dave,
Andy's link is to my post on your previous thread. The Serenatas were bought in very small batches for only a few Vodafone stores in the UK. When I visited Vodafone Oxford Street, I was told they only ordered in 5. They were bought directly from B&O Knightsbridge (who are not a franchise, but actually owned by B&O) as standard. So in answer to your question, the software on your Serenata from Vodafone will be identical to a Serenata for sale at a B&O dealer.
