Hi. I need an app to convert m4a to mp3 on my iPod. I have a few apps that convert files by uploading them to the cloud and then the conversion is done there and the converted file is re downloaded, but I would like an app that can convert the files on the device and without needing an internet connection. My iPod is jailbroaken on iOS 7.0.4, so I am open to ideas from Cydia or the app store. Thank you.
