    got as gift last night an psp slim as I saw on youtube and all videos but accidentaly upgraded it on 4.05 version. I've heard I can use it as GPS but all over the internet I found that I need a custom firmware or something like this. Can someone please teach me how can I downgrade it and not breacking my battery or something like that ? and I have to say that in the box , I've got no USB cable ... I only have the PSP and the charger and not a pro duo memory stick. ! Please help

    without a usb cable theres nothing you can do.
    then you need a pandora battery and mms

    search the forums on how to do it
    White Slim-->5.50GENB2
    Red Slim-->5.50GENB2
    PSP's modded so far--> 31+
