Cell Phone Knowledge Base

(As of: 2021-05-29)

Cell Phone Knowledge Base is a wiki for everything about  and their accessories, founded on February 10, 2010. Its focus is on providing quickly findable and easily editable information on old cellphones' specifications, features, firmware, software, battery pin-outs and their firmware and service manuals up to downloads, as well as some guides.

It was active in its first 2 years and up to 2016. Cellphones have since fallen into obscurity in the new age, but preservational projects have emerged on the game emulation front.
