Chat Heads, set free: jailbreak tweak puts Facebook Messenger all over your iPhone

When Facebook launched Chat Heads for iOS yesterday, the feature’s functionality was limited. On Android, Chat Heads cling to the side of your screen as your browse the web, type an email, or check your calendar, but Chat Heads for iOS are stuck inside the Facebook app. Just 24 hours later, developer Adam Bell has created a tweak for jailbroken iPhones that lets Chat Heads run “on top” of iOS just as they do on Android. “I just got jealous,” Bell says. “I wanted them on iOS.”
