You can either buy an iPhone on contract with Vodafone: http://www.vodafone.co.uk/brands/iphone/?ssSourceS
It is worth doing the maths, If you can pick up an unlocked 4s or one locked to Vodafone for a reasonable price then in the long run you would save money by staying sim only.

It all depends on how long you have left on your SIM only contract too
