I see that a lot of people are buying the Pandora battery from dealextreme, instead of buying a fake counterfeit Pro Duo from them, I will lend you one.
It will put Custom Firmware 3.80 M33-5 onto your PSP.
You will need to pay £10 deposit by Paypal, and send me a 1st class stamp when you post it back.
When I receive it back, I will refund your Paypal payment.
LIMITED TIME ONLY
I will send by 1st class postage, and you are required to do the same.
