Updating software on ps3
After more than three weeks of waiting, SCE have released an update for the PS3 which will allow users to change their passwords once PSN is back online.
The update (v3.61) is mandatory and is available now.
PUP and instructions to upgrade is available here (for US PS3).
Sony has made available a new system software (firmware) updates for Sony Play Station 3 (PS3), which has the version of 3.21, on schedule on April 1, 2010.
If using a PS3, your password can only be changed on your own PS3 (or a PS3 on which your PSN account was activated), as an added layer of security.
If you have never downloaded any content using your account on the system, an email will be sent to the registered sign-in ID (email address) associated with your account when you first attempt to sign-in to PSN.
This e-mail will contain a link that will enable you to change your password.
