I ordered a psp 1000 maybe 1001 off ebay. in the mean time i'd like to know is it mandatory for i to have a pandora battery? the seller told me the psp has the latest firmware (haven't received psp yet still in mail and can't confirm what firmware is on psp). do i need a magic stick - or can i use the usb cord and the *sd* stick it comes with? after installing a custom firmware can i still hook the psp up to the tv to play games and movies?
