iPhone 3GS 8GB on o2 ?

This is the Apple iPhone 3GS 8GB on the O2 network (can also be used with Giff Gaff) This iPhone is a year old and is in good working order. There are a couple of cracks in the phone as in pictures above (nothing that cant be fixed with a cover though!) and the home button sticks a little bit but it is in otherwise in great working order. The item comes with original box, charger, earphones & instruction booklets. This is a used item therefore it does have a few scratches here and there but this is due to general wear and tear. Perfectly working though. A brilliant little phone the best I have ever had. Selling due to buying the Samsung Galaxy S3 as I like the latest handsets!! Any questions please feel free to ask. 80 ONO
