I did some Googling recently, and was startled to find that no one was talking about PlayStation Mobile's DRM. You would think that since the service launched in October, someone somewhere would've been inconvenienced by Sony's protection. Then again, looking at the sales figures for some of these games, maybe I am the only one ... A few weeks back I found myself in a situation where WiFi was no longer something I could use on my Vita. I hadn't realized that without regular WiFi access my PlayStation Mobile purchases would become useless. I suppose it makes sense, when booting up a PlayStation Mobile game you're usually required to connect via WiFi to Sony's servers to authenticate the game. It appears Sony gives users about a 30 day grace period between needing a WiFi check up. What happens if you don't boot up a PSM game with WiFi running after 30 days? You get the message above, and are unable to play any PlayStation Mobile game at all. Thankfully, connecting to WiFi while playing one game will set your entire PSM catalog back to a playable status. You don't need to go through each individual title and boot them while connected to the internet.
