Maybe it is just sim-locked. Check out the unlockin applicaton for your phone.

Or else, 'sue' the ebay seller for selling you an un-usable phone. Unless the ebay seller specifically said that this phone is a lost/stolen phone, the seller shouldn't expect you (or any buyer) to perform an IMEI change.
