If you signed into PSN on your PS3 to, say, try to buy a Vita game, you'll have run into this already: surprise! There's a new mandatory system update. According to Sony, version 4.10 accounts for the change in the name of your account, from "PSN account" to "SEN account."

The update also makes improvements to the PS3 browser, including "improved display speed." We'd compare it for you, but the one time I personally tried to use the PS3 browser in the past, it froze my system and I had to pull out the power cord to reset. So if the new browser doesn't do that, it's a dramatic improvement.
