Swap Samsung Galaxy S2 (factory unlocked) and some cash with Galaxy S3 +

I have a Samsung Galaxy S2 in mint condition. I have used this for about 3 months. There are no scratches or marks on the phone. I also have the box and all accessories with original packing only charger has been used. I am willing to swap this and some reasonable cash with the new S3 (unlocked). Call me on 07590570701 to discuss further.
