The Sony Ericsson P800 is a smartphone introduced in 2002[1] based upon UIQ version 2.0 (which itself is based upon Symbian OS v7.0) from Sony Ericsson. The P800 is considered the successor of the Ericsson R380,[2] and initial design work was done within Ericsson, but it was produced after Sony & Ericsson merged their mobile phone businesses.
