Even cheaper is to convert your own battery to pandora like I did with my 2nd PSP.
No need to open the battery, there is plenty software that allows you to pandorize your battery.
Using a time machine IPL it still boots normal and you can swap memsticks once booted.
With this method it charges and plays like a normal battery.
Make a MMS for incase you need to unbrick \ downgrade some PSP`s.
Test the MMS incase you screwwed up and do not want to find out when you need to use it.
Now you can run multiple firmwares and have a pandora without spending a single penny.
Iam not planning to convert mine back to normal ever.
I got mine from dealextreme and it works well. As for creating a pandora battery, you need a fat 1000 or the first 1-2 models of the slim 2000. There's a nice chart in this thread: http://pspslimhacks.com/pspident-04-find-o...hackablepsps-1/
Thanks guys. I'm thinking I'll get it from deal extreme. I've had nothing but problems with ebay and as for making my own well I don't have a second battery and would rather just buy it lol.
