The Nokia 5510 is a mobile phone announced on October 11, 2001[1] and released in December of that year. The Nokia 5510 features a full QWERTY keyboard, an 84 x 48 monochrome display, and is notable for its digital music player, the company's first mobile phone with music player capabilities.[2] It has a 64 MB memory for storing audio files. Its successor is the Nokia 3300.

The 5510 shared many of the features of the
Design
Compared to other mobile phones of its generation, the 5510 is unusual in that it has an almost complete
The removable backplate on the handset was designed in such a way that pressure on the middle of the plastic could easily cause the plate to crack; this was highlighted in many reviews of the model at the time of release.
Music
The 5510 could play both MP3 and AAC audio files but not in their usual formats, instead the files must be encrypted and packaged into a Lockstream Embedded (.lse) files, which was a DRM technology that ensured that the encrypted files could only be played on the device. This encryption could be achieved using the bundled Nokia PC Suite software. Additionally it could record AAC audio directly from its internal FM radio, or through its built-in 2.5 mm (3/32")
Software
The bundled version of the Nokia Audio Manager software was designed to encode music and transfer it to the phone via USB, but encoding would typically take several minutes per song and the software only ran under Windows. The design was that files encoded and transferred to the device could not be converted back to their original formats for playing on other devices.
However alternatives to the Nokia Audio Manager did exist, such as Nokryptia,[3] a cross-platform command line tool distributed as source code which by exploiting a special case of the Lockstream Embedded file format could convert MP3 audio files almost instantly to the 5510 playable Lockstream Embedded format. Nokryptia worked by prefixing the MP3 file with a special header that then allowed the MP3 to follow unencrypted (the tool also supported the reverse, removing the header to restore the original MP3 file, however this was only possible on files encoded by the technique and the tool could not restore a file encoded by the Nokia Audio Manager).
