I'm currently using a 4.1u system with cIOS r14. I'm not really interested in updating to 4.2 cause there's no benefits to doing so but, I am interested in making sure I've got like best possible IOS versions. I know I can use Dop-IOS to like update and stuff but, I'm not 100% on which versions I should have or, honestly, how that program really works. Really, this is just so I'll be able to play any game. Metriod Prime Trilogy and Mario and Sonic at the Winter Olympics come to mind Not that they don't work but, I just want to be that extra level of safe because, I haven't tried them yet. So if anyone can just give me some advice or any tips, I'd much appreciate it and, I'm sure someone else on the forum will as well.
