Apple Iphone 4s 16GB (on Vodafone) Black ?

Apple Iphone 4s 16GB. As new with box etc. I have had it in a TECH 3DO case since new. No scratches and the phone works perfectly. I have had it on vodafone for about 2.5 months. No issues with it. Work just bought me a Lumia so giving that a go instead. Realistic offers only please. 360 I think the phone is unlocked but not sure. Can delivery within 10 miles of Stechford. Cash on colelction/delivery only. Thanks Andy
