Likewise, this is an app that I used constantly on my Palm Treo, and I am frustrated that the Android platform doesn't have an app for this. I switched from Palm to Android to go to the supposed "best" and hottest system out there. What a dissapointment.
I used the CallRecorder do go over what my father would describe to me regarding various projects, from electrical wiring and subpanels (he's an electrical engineer) to stock market information. Similarly, I'd be able to review what various vendors or businesses would tell me regarding various products that I'd called about.
It was possibly the most valuable feature on my phone, and now I realize that in fact it is extremley valuable.
I, too, would pay to have a working version of call recorder that didn't require me to use the speaker phone.
