If your job requires recording conversations, then you might not consider buying a recorder if you already have a iPhone 3G or iPod because there is the Mini Microphone.

With the Mini Microphone you simple plug it in your iPhone or iPod and start recording. It will work with your iPod Classic 120G version and the Nano 4G without any additional apps installation but if you are using the iPod Touch 2G or the iPhone 3G, you will need to get the iTalk Recorder or Easy Recorder Application.

It is small and lightweight so you don’t have to worry about how to carry the Plug and Play Mini Microphone.
