I've recently bought a used PSP Go in good shape. It came with 6.35 PRO-B, so I left if on that firmware. Now, I'm really curious to know if the previous owner used the "10 free games" offer on the PSN store, specially targeted to PSP Go owners. Since the PSN Store should be back up by the end of this week, I want to find it out. But, in order to connect to the PSN, I will need the latest official firmware from Sony, right? Is it safe to assume that I can easily downgrade my PSP Go back to fw 6.35 AFTER updating it to the latest official firmware? And sorry if this has been asked before; I just need to be 100% sure. Better safe than sorry, and I don't want to lose my cfw ability for good.
