All I know is this:

Log out of PSN, Set the date to 2/22, sign into Wipeout, played TDR Reverse Time Trial - (does not have to be Phantom - any speed) - end of race, as it's saving, skip back to top menu - go to play online - can the PSN sign-in prompt (or hit ok - it worked either way for me) - and cancel / navigate back to top menu. Go to racebox, and "x" your way through quickly - and with a little luck, it'll say "Syncopia" - if not, skip back to main menu - and try this again until it does.

Honestly - that's all I've done - but I can't narrow things down more - haven't had enough time to find it.

I'd like to know what the actual conditions need to be, because I have not yet narrowed things down. Stupid work, I'd rather be playing Wipeout.
