After some advice please. Recently purchased a new PS3 (3.40), and ordered a Mimimus to jailbreak (yet to arrive). Although I have a PSN account, I haven't been able to sign into it on the new console, because each time I try, I get prompted for the new system update (which patches the jailbreak exploit).
Anyway I copied across my game saves from my previous console, and tried loading a file to play a game today. I keep getting the message "this save file is not yours and cannot be loaded". I've done a search, and from the sounds of things, because playing the game unlocks trophies, unless I'm logged into my PSN account (which stores all the achievement details) I'll have to start the game from scratch!
Can anyone advise otherwise? If this is the only way, then I'm going to be screwed on all my other games too! Does the jailbreak allow you to get around this issue?
