A new PlayStation Update (version 4.30) was released yesterday, Tuesday, October 23. This updated effects a few things, one of them being the trophies. They will now be displayed by reallocating them to the networking portion of the XMB. So, when you want to view your trophies, you will have to go under network and your trophies list will be there.
Over the past few months many PlayStation 3 owners have been very upset that they couldn’t view there vita trophies from there PlayStation 3 but yet they could view there PlayStation 3 trophies from there vita. Sony listened to the feedback of the community, and starting this Tuesday for the first time you will be able to view your vita trophies from your PlayStation 3. In addition you wont have to go all the way to your friends list to see your gamer card anymore. Now to view your gamer card you will just have to go to your trophies and it’ll be displayed at the top of the page.
By the beginning of November the application known as Life With PlayStation will no longer be available to new users with the 4.30 update and, all applications will be gone including Stanford University’s Folding@home. This application helped Stanford University try to find a cure for Alzheimer.
