Apple iphone 32gb black no service *

this is my apple iphone 4 32gb black which was lost and claimed and then found it with a crack screen as seen in the picture. it works perfect apart from making and receiving calls and txt in uk. screen is broken as seen in the picture and can be replaced at £15 on ebay or elsewhere i guess. it will work outside uk as its blocked in uk now. was on o2 uk network. everything else works fine and only problem is no signal in uk and partly broken screen. cash on collection only or may accept paypal.
