From news article:
Then many Americans familiar with the RQ-170 carefully studied the pictures of the "captured" RQ-170 and immediately suspected something was off. For one thing, the RQ-170 shown was the right size and shape but the wrong color. Not just a different color from that seen on many photos of the RQ-170s in Afghanistan but also a color unknown in American military service. A closer examination of the Iranian RQ-170 photos indicated that the Iranians had reassembled an RQ-170 that had crashed and broken into three or more pieces. Then the Iranians apparently gave the UAV a new paint job (which was obvious to anyone seeing those photos.)

At the moment, the only things one can be sure of is that the American operators of the UAV lost the satellite signal connection with the RQ-170 and the aircraft eventually crashed. There was no indication of Iranians jamming the satellite signal. Iran has jammed satellite signals before, but only with wide area entertainment programming, not encrypted UAV control signals. Thus many mysteries remain but some have been cleared up because the Iranians could not resist creating a photo opportunity.
