So that means we should be able to use both the internal and external drives right?
Any idea when it will be available for non beta users? (And how does one sign up for beta)?
"You can download and install applications directly to your extra storage, and the saved contents are easily manageable through the settings menu.
Also, all the applications saved in the external HDD will appear in the Content Launcher of the Home Screen so it’s easy to keep track of what apps you launched recently."
You missed out on beta sign-ups a few weeks ago. There's no date on when FW 4.50 is out officially, but it should be within a month or so.
