Well the phone flaws are:
1) A broken sim reading pin which i repeared(I managed to unlock it and use it, before trying to put it back together). So its working, but i feel I have to mention that it had a flaw there.
2) The connect pad where the white battery cable was solder got removed. I manage to solder the white cable, but the phone had a boot problem. It only boots when its connected to power or usb. My guess is that somewhere it doesn't get power from the battery. I checked the battery and its power was ok 3.7.

I can't seem to be able to fix it and i m selling it for parts.
I just need to know how much a broken iphone can sell for parts?
I'm trying to get around 200-250 dollars to minimize my loss. Is it too much or too little to ask for?
