I have used iTalk for years now and it has served me well. The UI is very well designed and simple to use, the recordings are extremely high quality (on "best" mode"), and its very easy to transfer recordings from the phone to the computer. I highly recommend giving iTalk a try if youre in the market for an app to make and manage your own recordings on the iPhone.
