The Nokia 5320 Xpress Music is a Symbian S60 smartphone, released by Nokia in 2008. It is an XpressMusic series phone, which emphasizes music and multimedia playback. Among its highlights are a dedicated audio chip for better sound quality, 24 hours of music playback, a 3.5 mm audio jack, N-Gage compatibility, and music/gaming keys. A firmware update for this phone is available (version 4.13) which solves most of the issues of the previous versions.
Version 4.13 can now be hacked using the HelloOX method, allowing the installation of unsigned applications.
With firmware update 5.16 (still not officially released in all regions) the phone can now play MPEG4 and 3GPP5 video files up to 25 frames per second. The HelloOX hack has been said to still work on this revision.
