WorthPlaying writes, "On Monday Sony announced it was giving away four free games to PlayStation Vita owners in order to celebrate the one year anniversary of the portable console in North America.
In order to download the four games, you were supposed to access the PSN store via a Vita. And, for the most part, that was true. When the PSN store updated on Tuesday evening, the “purchase” option for the four games was removed from the PS3 PSN store and the Sony Entertainment Network PSN store on the web. However, Sony seems to have forgotten that the PSP can also access the PSN store."
