Hey Joe!
Yeah, we are trying to soft mod an older PSP phat battery. We didn't have much luck. I figured I would see if someone around here still messes with PSP's and would have a pandora battery & mem stick on hand.
I have a brand new keg of delicious hefeweizen on tap in the garage that you are welcome to if you stop by.
Thanks.
Joe... let me know if you have any more luck with your battery. I'm bidding on one on Ebay as well. I may also just buy a new battery from Best Buy and hard mod it as a last resort.
