do not i repeat do not upgrade past 5.03 or you will not be able to do a grip of things that you can do with other updates!!!! What it does is makes it impossible to play iso and cso games on your psp and what i have heard is it doesn't allow you to play ps1 games if you upgrade it that high also. so stay under 5.03 or your psp is crap just like the ds.
