Ok so Apple gave me a new 3GS. Activated it with the original sim, then ran Blackra1n and Blacksn0w to unlock it. All went well, but when i put the sim i want to use, i get the "different sim detected" on iTunes. I tried restoring and doing it all again, but it didn't work. Something missing? I'm on 3.1.2 and my 3GS has the new bootrom.
