i am sure because i asked the nearest Telenor shop and service, they said that n900 need to be decoded - price 35 euros,
and i wont pay until i update to pr 1.3.
here is one more screenshot about the sim lock:

it is always that simbol no mater what sim card is in it.

i also tried flashing pr1.1.1 and after that i flashed kernel and roofs from pr 1.3
the phone booted up whit some errors during the boot and after,
and i checked about product option and for version i got unknown and os: unknown.
so i flashed back to pr 1.1.1 because i want full working pr 1.3 or pr 1.4
