This make you appear offline using mecomment, and wipes history. It is stealthed as Mobile Suit Gundam: Crossfire-BLUS30017, if you play this game you suck... Its the second worst game on PS3.
- Sign off before using, it will not show until you go off then back on if you use it while signed in.
- In menu press X to appear offline
- Press Circle to appear online again (it adds a blank mecomment so you can edit your comment normally)
- Press Triangle to wipe history
I doubt this will save you in any way from Sony but you never know. It's more for fun and to get away from annoying friends.
Should work while playing a game too but i haven't tried it but i will tomorrow. Also it's my first menu, i have a wide screen tv so i'm not sure how it will look at different sizes and resolutions please lmk...
