The two services will initially be available for users in North America (where the service could resume late Saturday), Europe, the Middle East, Australia and New Zealand. Service in Japan and Asia will return at a later time yet to be announced.
First services to return will be online gaming, playback of already rented video, "Music Unlimited" online audio streaming, access to third-party services like Netflix and Hulu, PlayStation Home and friends features such as chat. Full service is expected to resume by the end of May.
PlayStation users will be prompted to download a software update when they first connect to the network. The version 3.61 update will ask users to change their password. Once changed, users will be able to sign in to their accounts.
The login password for each account was among the data stolen when an unknown hacker or hackers attacked Sony's San Diego data center on April 19. Other information leaked included the names and addresses for registered PlayStation Network and Qriocity users, along with their birth dates, e-mail addresses and other personal information.
Later, Sony discovered a similar attack on its Sony Online Entertainment network, which serves PC users. That service will also resume worldwide on Sunday.
