I also had a 1.5....
but I have recently tried to "flash" my psp on my own...took a big
risk..
and now my firmware reads 3.02.....
and the best thing is, can surf web, and can also play
"homebrews"
those of you interested, can see this website. Follow the
instructions, that's what I did.....but please hor, read carefully,
don't end up bricking your psp...don't come and find me...
