To quote: Next Tuesday, October 23rd, we will be releasing a new system software update for PlayStation 3 (version 4.30). With this update we have made several changes to how Trophies are displayed on your PlayStation 3.
The Trophy Collection will now reside under PlayStation Network on the XMB. Trophies that you have earned playing PlayStation Vita games are now displayed on your PlayStation 3. You will also be able to see your Trophy level and progress towards the next level while viewing your trophy collection.
By the beginning of November 2012, we will retire the services available through the Life with PlayStation application. In conjunction with its retirement, we will stop offering the Life with PlayStation application to new users with the 4.30 update.
