PlayStation Network have resumed some PSN services as promised on Sunday, probably not the way we were expecting. It is confirmed that PSN is back up in Japan, hopefully the UK, the US and other regions will follow shortly. Sony announced that online gameplay for PlayStation 3 and PSP and access to account management features will go live this week. However, other features, such as the downloadable games shop, will not come back online until later this month.

The company suffered a massive security breach in the past fortnight with the personal details of 77m users, including credit card details, falling into the hands of a hacker. Following this incidence, Sony has implemented a variety of new security measures to ensure greater protection of users' personal information. All PlayStation 3 users will be required to download a system update and to change their passwords. Sony will give each user 30 free days of PlayStation Plus premium services and a selection of free downloadable content, as an apology to its users.
