Nokia Eseries
The Nokia Eseries is a discontinued line of business-oriented smartphones running Symbian OS, produced by Nokia from 2005 to 2011. The Eseries brand became the partial replacement for the top-line products of the Nokia 6000 'Classic Business' range - the 6000 range itself would turn into a mid-range line with broad appeal beginning in 2007 mostly using the 'classic', 'slide' and 'fold' monikers.
