Still Sealed iPhone 4s Black 16gb ?

Its on tesco so o2, giffgaff etc should work fine, but they can be unlocked cheaply anywhere if needed. Still sealed with the plastic wrapper. They are selling around 395-420 still on eBay. So no silly offers at 300... No rush to sell but first decent offer takes it. To make me an offer or ask any questions please text or phone. Thanks for looking :)
