Samsung galaxy s2 Swapping for iPhone and cash +

Willing to swap my White Galaxy S2 with box and charger only had for 3 Months very good condition for a iPhone 4 or 4S. If you contact me with what you have I can give you an offer of Samsung galaxy s2 plus some cash. The handset is unlocked to all and I will require either a vodafone iPhone or a Unlocked. Includes Micro-Sim adapter so you can use your current iPhone SIM. Contact me by text for the quickest response. I can travel to any reasonable distance. Thanks
