iphone 4s 16GB Black ?

Hi. Up for sale is a stunning iphone 4s 16 GB which was bought for my partner only six weeks ago and was only used for 1 week before buying a samsung for her because of itunes which she cannot get her head around. I purchased brand new for 400 and would like to pass this phone as brand new although it was used for a week then back in the box. Vodafone and also unlocked for any sim with the latest i06 software. Will not dissapoint the buyer. Please only genuine enquiries. Thanks!.
