Nokia Smartphone Hacks: Record a Phone Call

From time to time, one often needs to record phone conversations for business or personal reasons. For instance, when one orders merchandise over the phone, one probably wants to keep a record of exactly what was agreed on in case a dispute arises in the future. On a landline telephone, one can use an answering machine to record phone conversations when one talks with lawyers, accountants, technical support, or even sales agents. But for mobile phones, the "Answering machines" are located in the operator's server room. They record messages for missed calls but do not provide a way to record a conversation once they pick up the phone.
