"Even if you're not an investigative reporter, private eye or just plain creepy, there are a lot of times when being able to record a telephone conversation could save your butt. In the past, wires and microphones were an essential part of documenting a call, but now all you need is this compact Mynah handset. Named after a bird that's capable of mimicking humans, the handset connects to your cellphone via Bluetooth and has enough storage to record 340+ hours of calls on its lengthiest setting. Obviously if you want higher quality, you'll be able to record less.
It has a host of features for documenting the date, time, number and duration of a call, and you can set it to record everything carte blanche, or only when you specifically tell it to. And like with a TiVo if you get halfway through a call and realize you probably should have recorded it, the Mynah actually records it all along and will simply save the entire call when you tell it to. The recordings can then be uploaded to your PC via a miniUSB connection, and on a single charge the handset is good for about 8 hours of record time. The Mynah won't be officially shipping until December 28, but you can order one now from their site for $249."
