Narrative:
During preflight departure checks. Flight attendant informed the captain that a passenger's cell phone was accidentally dropped in the sidewall next to a window seat. Maintenance was unable to retrieve the dropped cell phone. According to the maintenance MEL the item/issue could be deferred. However; most cell phones contain some type of lithium ion batteries which have been known to cause a fire hazard in certain atmospheric conditions/environments. Operating a class ii navigation/ETOPS flight with no immediate diversion options should a fire situation arise presented a situation the captain was not comfortable with. Therefore; the decision to declare 'unable to operate' was made; and I as the first officer fully supported.
