Sony had promised Playstation Network users that the network will be up and running this week, albeit in its most basic form. We have yet to see any evidence of this and the week is nearly over.
All is not lost however, it appears that a select few gamers are currently testing the The Playstation Network for Sony. Presumably this is a kind of beta test type of thing before the full network is rolled out.
On of the lucky users is SignOfZodiac, a gamer who has just posted a video to YouTube. According to the video, there is a firmware update. This is no official word of course but the signs are promising.
Check out the video below.
