Back at Mobile World Congress, Samsung filled us in about its Knox security suite, and now it's just announced that it'll ship on the Galaxy S 4. In case you need your memory jogged, Knox focuses on providing enterprise security on your handset while letting personal content live on the same phone. Like BlackBerry Balance, Knox can keep apps, email accounts and content related to work in a secure sandbox, while personal things will sit just outside it. Though the GS4 will nab it first, Knox is set to arrive on other Samsung devices. Gallery:
