Just a tad ahead of schedules -- perhaps as a macabre assurance this isn't some April 1st joke -- firmware 3.21 for the PS3 is now being seeded to anyone who tries to log onto the PlayStation Network. As far as we can tell, all the update seems to do is remove the "install other OS" option and kill access to anyone who does have another platform dual-booted. Just a friendly reminder, if you fall into that category, be sure to either backup your partition or wait for Geohot to find a workaround.
