I have been outta the psp scene for a while so I have no idea whats the latest greatest thing! I have 3 psps, 2 phats and a slim. One of the phats is on 5.50 GenD (Full), the other is 5.50 Prometheus and the slim is 5.50 Gen D3. My question is which one if any is on the newest cfw and where do I go next with them to get them updated. Thanks for any info.
