Is this possible? My friend has a hacked slim, and lent me his silm pandora battery which doesn't work with my fat psp. If I lend him my fat battery can he make it a pandora with his slim? are the steps any different than making a slim battery pandora using a slim? The main difference between the two is his is slimmer and lighter and doesn't connect up with my psp. His is a 1200MaH and mine is 1800MaH. If he can succesfully make my battery a pandora the MMS stuff can be done by me with my fat psp correct? Thanks, Conor.
