What the hell does this have to do with the OP's question? This has nothing to do with Aegis. Lock state is generally stored somewhere on or near to the ROM baseband chip. There is no real way to reliably write lock state on the N900, it's going to be even more unlikely on the N9.

I don't see why the N9 wouldn't be capable of being SIM unlocked via code, if indeed operators decide to lock it.

N900 was done via #PW+CODE+1# as far as I know. The better option is to simply buy it unlocked
