To continuously enhance the overall PlayStation 3 experience, Sony has released the firmware 2.17 update for the PS3 today. To download the update, simply turn on your console and log into your PSN account.
Try not to get too excited, however, the firmware 2.17 is nothing more than a mere technical update to augment the PS3’s online gaming capabilities.
"The operating stability of some online PS3 titles has been improved,” Sony commented.
So do not expect anything huge such as new design scheme or features. The update should not go unnoticed however, as many PS3 online titles such as COD4 could benefit from this significantly.
