Hacking your PSP may cause it to become bricked. Essential this means it goes into a non responsive mode in which it wont do anything and you will have to contact sony to have it unbricked - but since it only becomes bricked from playing around with it you may find that they wont fix it without a fee as you are in breach of your waranty.

No, hacking iTunes is not safe.

Hacking IS illegal.
how to be safe from hacking
Flashing a PSP is basically hacking it to read programs it normally wouldn't read.
Hacking the PSP only changes the firmware. You can freely replace the screen, with a screen from the same model of PSP.
No only if you put cfw (custom firmware) on it by hacking.
It allows you to get homebrew and other goodies not on the PSN store
yes but you cant play it on the psp if it isent hacked
it depends.. if you caught you will get arrested.. ♥♥♥♥
Yes it's safe.
