With TheGamingReview covering iPhone games as well as consoles, it seems like a match made in heaven that Sony have released their official (and very free) app onto the iPhone app store. Available (for free) from this link, the app lets you see which of your friends are online, as well as checking up on your trophies. There are also options to see news updates and information about your PS3 games, and the whole thing look very slick and well made. It’s also available on the Android store, if that’s the team you bat for.
Did we mention it was free?
