MP3 is a format for compressing audio files including music. It allows you to fit a lot of audio (which usually takes up a lot of space) into a much smaller space, by removing the bits of the sound that you're least likely to miss.

With the progress of mobile phone technology, mp3 mobile phones have become available to UK customers.  Mp3 mobile phones offer more than just the traditional functions of calls and text messaging, and go even further than camera phones and video recording – they offer the experience of mobile music, allowing users to listen to mp3s wherever they might be.

Features of mp3 mobile phones can include:

    •The ability to play mp3s combined with the other functions of the mobile phone, providing greater convenience than using separate mp3     players and phones.

    •Compatibility with services such as iTunes, letting the user download new music with ease, and formats such as Windows Media Audio.

   • Software to make transferring mp3s from CD to phone an easy matter.

    •Wireless mp3 transfer.
