Does anyone have any reccomendations for this? It seems to be a bit of a minefield, as far as I can tell the best to use is either m33 3.52 which permanently updates your OS or devhook which is temporary. Devhook seems to have a lot more messing around whoch is more chance for me to brick the psp I guess!

Anyone have one/hacked one, who can share their thoughts?

Thanks
