Im new with psp pls hlp me?

if you bought the PSP 2000 series, then congratulations, you need to take it back to the fellow you bought from and tell him/her that you want to be able to play downloaded games. its too complicated to modify it yourself. then go to Yahoo! and search PSP game titles. if you bought the PSP 3000 series, then sadly to tell you that, if you want your microphone (for skype) to be intact, theres no solution for you to play downloaded games yet, just have to be patient like i do. (i have the 3000)
