Facebook Messenger iPhone app lets you voice chat with your friends

Vivox offers a Facebook app which allows you to voice chat with your friends as you browse the site from your desktop, but what about while you're out and about? A mobile option would be nice, too. That's what the developers at Crisp App think, too, and its iPhone app lets you do just that.

Grab Facebook Messenger for $2.99 in the App Store, and you'll have a convenient way to voice chat with your Facebook friends on-the-go. Select a friend's name from your contact list, tap the call button, and they'll receive a link to complete the connection in their current Facebook tab. Once your friend clicks through, your VoIP chat session is ready to go. GigaOm reports a slight delay on both the desktop and iPhone app, but overall reviews are very positive so far.
