Blackberry Torch for IPHONE 4

Is anyone looking or whilling to swap me a Iphone 4 for my Blackberry Torch 9800, it is in perfect condition and everything works on it. Is a really good phone and has full touch screen capabilities as well as a qwerty keyboard but I just prefer IPHONE's. Might consider IPHONE 3GS as well. Please text or mail me if you are interested thanks,
Robert
