It seems I’ve made a wise decision for not turning on my PS3 for the PS3 3.21 Firmware update (ok, I lied, I haven’t turned it on for ages), because it looks like there are more bad news to it other than the removal of the “Install Other OS” feature for the phat PS3. It has been reported that many users are experiencing some problems such as not being able to load a disc, log onto PSN and some even as serious as not being able to turn on their devices. What’s weird is that there are users who did not encounter any problems at all and the problems seem to only appear randomly. Let us know if you've encountered any glitches after the update.
