I've heard many users say they'd like to see an application that allows one to record phone conversations. Nextel phones have it so I assume blackberry's should ALSO have it.

Voice Recorder/Phone Conversation Recorder with the option to email the conversations to your email for playback.

Today I bought software through a company that only allows directions through the phone...so I had to go purchase a tape recorder to record...If my blackberry did it I could've just used my phone instead!
