Factory unlocked white iPhone 4 (16GB)

Hi

I'm selling white 16gb iPhone 4. I purchased it from Apple Store and it is still under warranty until May. It is factory unlocked by AT&T and now can be used in other carriers in USA as well as other countries. It comes with the original box, cable, charger and push pin. The condition is pretty good except few small scratch in front side. I'm asking $400.

Thanks,
