IPHONE 4 WHITE 8GB ON ORANGE SALE OR SWAP ?

I am looking for a quick sale/swap for my white iphone 4. The phone is on Pay as you go on orange. I orginally bought it in Jan this year but it was replaced in May due to a fault so its really only 5 motnhs old. I am looking for 230 in cash or another smartphone like a lumia 800 plus £50 my way. open to most offers just request that the phone i swap for is in good condition like mine. It has always been in a case and has never not had screen protectors on it so it is scratch free. Let me know by email and i will get back to you asap. Regards!
