Facebook for every phone app for Symbian and other Java/J2ME supporting phones (including the new Belle Refresh/FP2 devices – Nokia N8, 808, 603, 701, 700, 500, E7, C6-01, X7, C7 & E6) has been updated to version 3.4.1 recently. There are several bug fixes and speed enhancements in Facebook for every phone java application. It is compatible with S^3 / Anna / Belle Smart Phones. Special thanks to Rene for sharing it.
The FB Java app has a very basic set of features and limited functionality which might be good for cheap, feature phones but certainly not enough for Symbian devices. However its been quite fast & responsive to use Facebook with their native application. Its indeed very sad that Facebook have not developed a native Symbian app. Fortunately there are some 3rd party apps to fill this void and fMobi is perhaps the best of these.
