Timbaland is releasing an album made especially for mobile phones- the first ever.

The 50 Cent and Justin Timberlake producer will make one track a month available via US phone company Verizon.

'Billboard Magazine' reports that Tim has promised each song (which will also come out as a ringtone) will feature a different artist.

The first track will feature his protg Keri Hilson.

Timbaland told 'Billboard': Just producing a mobile album has never been done. I'm the first to ever do it.
