ps3 region A and B

[ImStylinOnYaBro]

First off, I browsed through and coulnd't find anything after a few minutes of looking. Second, sorry if this is the wrong place to post, it seemed most logical to me being as its a software questions.
Does anyone know a good guide for the method on making a ps3 region free w/ pkg files and lv2 appp on some firmware 3.55? A few sites had the exact same guide, which in my opinion is poorly written, especially for someone who hasn't been in tune w/ the modding world.
