Hey, I just ordered this one off e-bay iHas 524-07 retail.
So I sent him these pictures attached to make sure it was an MTK chip set and he said it matches the MTK pictures exactly.
Before I sent him the pictures he said
"All we know is that it is revision "DU".
After I sent those pictures he opened up a box and checked it to compare and was the same as in the pic. So I went ahead and ordered it.
