The new Playstation 3 firmware 2.30 is now live on PSN. This is the update that contains the new software based Playstation store. More details on the update as they become available. I’m downloading it right now.
[Update]: So I finished installing the new firmware. The new store is pretty amazing. Right now not all of the pictures are uploaded, and the server is getting really hammered by people who want to see the store, but its still really fast and nice. I downloaded a wallpaper and it went nice and quick. I want to check it out tomorrow morning to see what it looks like with all the images loading, but I’ve gotta say that its pretty sweet. Nice job sony!
[Update]: This morning it seems like the images are all working.
