PSP firmware 3.50 is starting the slow process of integrating the PlayStation Network onto the handheld. When using Advanced Remote Play, users will be required to log-in using their PSN ID (pictured, right). Although this is a feature only applicable for those with PS3 systems, its exciting to see the PSN slowly appear on the system. Hopefully, this is a sign that future integration is not too far off: we can't wait to get a PlayStation Store
and a single user ID for multiplayer games. The future is looking quite bright.
