Ok so someone in my house just updated to 4.2U (because they wanted to play Lego Harry Potter), Is it really such a bad thing? Is the only downside to it that it won`t play out of region games. It seems to still play the NTSC backups I have tried. I`m thinking about going to the WODE in the future (mainly to play GC from HDD). So my question is what can`t I do now that it has 4.2 on it?
