Facebook has released a dedicated Messenger app for the iPhone. If you need to IM your Facebook friends while you're on the go you can use this new dedicated app. They have not released an app for the iPad so you'll have to do the 2x thing.

"Facebook Messenger is a faster way to message. Reach friends right on their phones, get and send messages fast, message everyone at once and more.

Top Features:

• Message friends, groups of friends or anyone in your mobile contacts
• Map your location, find your friends and make plans on the go
• Get mobile notifications so you never miss a message
• Include photos so friends can see what you're doing"
