Aside from wanting to record phone calls with my best friend, of which we usually do with GarageBand recording nearby... I'm wanting to record a phone call conversation with my dentist; of which there is a dispute concerning a bill. The dentist has already agreed to allowing me to record the convo, I just need to call him back and do so. I can only imagine if such an app existed, it would be a jailbroken one. I've read the laws and here in California all parties on the phone need to consent, over the recording.
