If you signed up for the PlayStation 4 firmware update 4.0 beta last month, then you may want to keep an eye on your email inbox. Beta invites are reportedly going out as we sit here typing this very article, so here's hoping that you've been selected as one of the chosen testers.

Firmware 4.0 brings numerous improvements to Sony's system - some of which haven't been detailed yet. The update adds folders so that you can organise your games and applications, grants the option to see hidden Trophies, and even refreshes various aspects of the console's user interface. All in all, it sounds pretty good, and we're eager to hear what else is in store.

Have you got your hands on an invite? Feel free to gloat in the comments section below.
