Apple iPhone 4S 16 GB - White - Vodafone - Boxed with Accessories - Like New with 9 Months Warranty ?

I am selling my iPhone 4s, it is the 16GB version and is locked to Vodafone. Vodafone told me they would unlock the phone for 20, so I believe you could do the same if your on another network. The phone is like new in excellent condition with no damage and no faults. It comes with approximately 9 months warranty with Apple (until 23/04/2013) so the phone is only about 12 weeks old. It comes complete in the original box with the wall charger and USB cable. Cash on collection from Cambridge. 325 no offers please. Thanks for looking.
