Nokia 8110: Nokia 8110 was the first of Nokia's high-end, 8xxx series of phones released in 1996. Its distinctive styling was the first example of a 'slider' form factor. A sliding cover protected the keypad when being carried in the pocket and extended downwards in use, bringing the microphone closer to the mouth. The action of opening the cover also answered an incoming call. The prominent curvature of the case, particularly when open, earned it the nickname "banana phone".
