im a graphic designer, so keep in mind i know almost nothing about programming. its not my thing, so excuse me if this is a wetodded idea.
i was thinking that maybe the 2.0 browser could be ripped from the psp's HD, and run as either a homebrew or actually have an icon on the main menu for 1.5 or 1.0. we know we can add to the psp's HD other than updates. its been done with pspersonalize.
just a thought. now flood my thread with reasons why it can't be done
