IPHONE 3G... no signal, but easy to get fixed in any phone shop !

I PHONE 3G for sale Will swap for a 6 bedroom house or a new Mercedes... Only joking :( but will consider an exchange for something of equal value Got this a couple of years ago and has been lying around. Says O2-UK when I put my sim in but no signal, so must be blocked. This is easily fixed. Few srcapes on the back, screen is fine. 8GB Phone works fine technically and connects to internet and can be used as ipod for example Make me a reasonable offer Thanks 07732871554
