IPHONE 4 WHITE 16GB FOR SALE OR SWAP ?

Hi All I am selling my iPhone 4 in White 16gb. The phone is used but in excellent working order and comes boxed with original charger and new original headphones. Reason for the sale is I lost my work phone and need to replace that asap. I am either looking for a swap (good blackberry plus cash) or just cash. I am in need of two phones (one to replace my work and one to replace the iphone that I am selling) Interested please email me asap. Cash on collection only and I am willing to drop off today. Thanks
