Looking to swap Blackberry Curve 8520 locked to Orange ASAP ?

Hi I am looking to swap my Blackberry Curve 8520 (locked to the Orange network). The phone is in perfect working order, I just fancy something different as I have been using Blackberry for quite a number of years and would like to try something new. Would anyone care to swap for an Iphone 3, Samsung Galaxy S2 or an HTC of some kind? Please let me know if you are interested Thank you
