its a psp phat 1001 i am trying to mod it for his birthday i don't have a Pandora battery, or a MMS. It has 6.00 OFW so my question is can i do it w/o the Pandora and MMS? if i cant how much is it going to run me to mod it. (as a side note it also needs a new switch (like the metal part on the inside) and the switch on the out. side if i could get some help with that to that would be nice)
