(IGB Eletrônica S.A., trading as Gradiente) are an Brazilian electronics company. Founded in 1964, they produced electronics with a focus on home entertainment, and later became particularly known for their clone consoles made for the unique market in Brazil. They created the Phantom System, the most popular NES clone in Brazil, which resembles an Atari 7800 with Mega Drive pads. 

Later, Gradiente collaborated with Estrela (a toy manufacturer) in around 1990, and they began officially representing Nintendo in Brazil, as Playtronic. (Similarly, Tectoy represented Sega in Brazil).

In 1997, Gradiente established a joint venture with Nokia, and began manufacturing Nokia’s mobile phones within Brazil.

Seven years before the first Apple iPhone was released, Gradiente had actually filed for the brand name “iphone”. They manufactured Android devices under this name.
