Is that correct. What about pins layout. Witchone is correct?

Ill be very thankful for any info about that phone. I try to unlock him alredy 3 weeks. Is it possible that this pfone is not unlockable. I dont think so. Must be some solution. Ill try to find C-BUS in some hole left to SIM holder. If i unlock that peace of sh$%t i tell you.
