Facebook Messenger
Price: Free
Current Version: 1.0.1
Size: 5.8 MB
Requirements: Compatible with iPhone, iPod touch, and iPad. Requires iOS 4.0 or later.
Facebook Messenger lets you send messages directly to your FB
buddies' mobiles. Of course, that is possible only if they have
registered their mobile numbers with the social networking giant. If
not, then the message still gets through to their wall. On installing
the app, it asks you to register your mobile number with FB in case you
haven't already done that. The app not only lets you start messaging
right away, but it also retrieves your online FB chat history and
reflects it in the app interface. It is effectively a trimmed down
version of the original FB app, with the sole purpose of allowing you to
message your friends. The app does appear to serve that purpose very
aptly. It also supports location services, thus allowing you to let your
friends know about your current location using your phone's GPS. Some
of the interesting features of this app include group messaging, mobile
notifications even when the app is not running, and the ability to
include photos so friends can see what you're doing.
