@ash: Pandora and DCv* are basically the same. When the unbricker was first released it was called Pandora. This unbricker consisted of a 'magic memorystick' and a 'service battery'. Since the first release D_A improved the magic stick files and called it Despertar del Cementerio (DC). We are now at revision 5 (DCv5). The battery part remained the same, as it didn't need any upgrades. So to conclude: When people speak of a pandora's battery, they mean the actual battery which is in service mode (hardware part). DCv*, covers the files on a memstick which do the actual unbricking/unlocking (software part). So if you have a pandora's battery and a memstick with any DC version you are set to unbrick and unlock psp's. Hope that clears it up for you.
