Its gotten harder since I jailbroke mine about 1.5 years ago. I think that redsn0w might have a jailbreak for 6.0.1 but I am not positive since i am running an old version. Also before jailbreaking it you should know that hackulo.us (the source that lets you get installous and basically download apps) is down, may have been busted by government i dont know, so you wont be able to get the free apps. Free music though.
This is the only place I found to download(again not sure if legit.)
I used redsn0w when i did mine but a different version.
