I think mine is a v7 i just bought it and the # is SCPH39004.
Anyway i ordered i Messiah 2 from Charlie,Dust2dust (thanx)

and its should be in my hands during next week, so when and if i get it and chip it then i ll tell you for sure if mine is a v7.
For sure my old 30004R is a v4 but the neo 2.2 messed around with my laser.
