Just been offered an Extra line on my contract as an existing customer with Vodafone for over 2 years.
The deal is FREE HTC Wildfire which is an android mobile with 5mp camera worth £230 300 mins, unlimited text and internet 24 month contract
My current contract finishes in December and they said I can cancel that when it expires and carry on with my extra line for £10 month.
I was offered other phones like HTC Tattoo, Nokia 5230, Samsung Monte etc. but the HTC Wildfire is by far the best one.
