Facebook has launched a new mobile application that will give users around the world a full social experience on over 2,500 phones. The new app is obviously targeted for people with dumb older phones. The Facebook mobile profile gives the full breakdown on what users can expect:

“This app not only includes Facebook’s most popular features, such as News Feed, Inbox, and Photos, but also enables you to upload photos and find friends from your phone’s contacts.”

As you might expect, users will be charged for the data they use. The good news is that Facebook collaborated with 20 mobile carriers worldwide to provide the app free of charge for the first 90 days. The list of carriers offering free data access is Aircel (India), Airtel (India), Banglalink (Bangladesh), Beeline (Russia), Celcom (Malaysia), Etisalat (Egypt, Nigeria), Globe (Philippines), Idea (India), Indosat (Indonesia), O2 Telefonica (Germany), Reliance (India), Smart (Philippines), Smartfren (Indonesia), Telkomsel (Indonesia), Three (Indonesia, United Kingdom), TIM (Brazil), TMN (Portugal), Ufone (Pakistan), Vodafone (Turkey), XL (Indonesia).

One ting worth noting is that Facebook says the app is optimized to use less data than other Java apps, making it more affordable once the free 90-day period expires.

You can download the app by visiting m.facebook.com and scrolling to the download link, or enter d.facebook.com/install directly into the mobile browser. You can also find the app in various app stores.
