Thanks for the expressive one answer !?
I cannot try it, becaus the phone is not my phone, i want to buy the phone! So, if i could unlock the bootloader with a Sim-unlock,
then i buy the phone & buy the sim-unlock(code). If i could not unlock the bootloader, i am not interesting to buy this locked-phone!!
My consideration is: Buy a cheap locked-phone & unlock it by my self (+pay the unlock-code) OR buy a expensive unlocked-phone!!
... or don't pay for the damn unlock-code an hack the damn bootloader, so that i could change the "bootloader unlock allowed" to YES!
