iPhone 4S Black 16gb - blocked in UK for aboard Only !

I owned this iphone 2 weeks originally brought it here on Gumtree. Look like the guy sold this to me did the insurance job, the phone now is blacklisted and will not work here in the uk, but good working if you decided to take it out of the country. The phone is in good condition comes with charger. Please only reply if you interested. Its cash on collection ONLY i will not post anywhere (collect in stepney green/Mile end,East London area). Thanks for reading.
