Iphone 3gs 32GB and psp or cash for your BB Bold 9900 ?

I have an iphone 3GS 32GB in black. Has box, 3 cases, screen protector spare and one on it. Has minor marks on the back and excellent front. In great condition overall. Also has plug, and 2 usb connectors so one for the plug and one for the computer or laptop. I want to swap this and cash your way for a BB Bold 9900 or i also have a psp e1003 i would put instead of cash. Just get in touch, You must drop or meet as i dont drive but could get public transport. Text or email and i will get back to you asap. Thanks.
