I recently upgraded to a new phone after my 16GB IPhone 3G screen cracked. Needless to say, I am left with this IPhone/MP3 Player/Video Playback device which I would like to sell. However, I have no idea how much it's worth!

Here are 2 pictures of the IPhone:

As you can see the crack is pretty minor in comparison to some breaks. The crack itself only affects the upper part of the screen where the clock shows and does not impact anything else on the screen (ie. buttons, video, etc...)

If anyone has sold one of these before or has any idea of how much i can get for it please let me know. A friend of mine is willing to buy it but I literally have no idea as to how much it is worth. Any feedback is greatly appreciated.
