The Nokia 6310i is a mobile phone from Nokia first introduced at the CeBIT fair in March 2002 with sales starting later that year and discontinued in late 2005. It was primarily marketed as a business phone and for some years was the dominant GSM device in the corporate world. The device was most commonly offered in Two-tone Silver/Grey or Two-tone Gold/Black trim, the Copper coloured variant being much rarer. The model is basically the same as the earlier 6310 from 2001, with the addition of tri-band reception, Java and a blue-backlit LCD Screen (as opposed to the earlier green backlighting).
