iPhone 16GB Black Vodafone Excellent +

I have for sale my Iphone 3GS 16GB in Black. Comes with charger and case and USB lead Excellent condition !! It is on Vodafone network so you will need a Vodafone sim card.. I believe Vodafone will unlock the phone once you have a Vodafone sim card even pay as you go card for 20...This will be a permanent unlock
