Chat Heads displayed in Facebook's messaging feature.
Facebook version 6.0 brings the Chat Heads contact feature to Apple's platform, though in a more limited capacity than they appear on Facebook Home. The pop-up contact bubbles appear only in the Facebook app, and they are unable to integrate with a user's SMS contacts.
Recently Facebook was rumored to be working on bringing the "immersive" experience of Facebook Home to Apple's iOS and Microsoft's Windows Phone 8 platforms. Those rumors, though, were quickly shot down by knowledgeable sources, who said Facebook has no plans to port the Home experience to either platform.
The update also brings the ability to send "stickers" — giant, emoji-like pictures — to other users. The stickers come in packs of related pictures and are currently free. The ability to send stickers is currently limited to the iPhone, but any device can receive them.
The update also packs a redesign of the News Feed, making it cleaner and more easily accessible. Version 6.0 of Facebook for iOS will be rolling out for free for iPad and iPhone users later on Tuesday.
