The M4P music files you purchased from iTunes store is protected by DRM, they could not be played without iTunes, iPod, iPhone etc Apple's product. So you could NOT play them with AT&T mobile phone. You need some software to convert the protected M4P music file to unprotected MP3, WAV etc first, then you can play the mp3 files with your portal MP3 player.

ShareDRMusic is such a software to convert the M4P music file to MP3, WAV easily. You can click here to download ShareDRMusic and convert them to MP3 files and play the music files with portal MP3 players.

There are two methods to bypass the DRM control before.

The first one is to burn a copy to an audio CD and then rip/encode it. This method is legal: the terms of use for iTMS purchased tracks legally permits you to burn regular audio CDs from purchased tracks, and it still fair use to rip CDs you have a license for. But this method is too complex and expensive.

The second one is to use a recording software and sound card. TuneBite, SoundTaxi, WMA Converter are software tools of this kind.

Share DRM Music will automatically do the followed procedures for you:

> Burn a Virtual audio CD with the protected audio tracks
> Rip that new Virtual audio CD to MP3's.

Share DRM Music allows user to burn music to a Virtual CD-RW disc on media players, and then automatically rip/encode the music stored on the Virtual CD-R. This makes the whole conversion process automatically and faster.

In October 2006, Jon Johansen announced that instead of breaking FairPlay, he had reverse-engineered it so that other companies could play their DRM-protected music and movies on iPods and Apple's new Apple TV. His company, DoubleTwist Ventures, would license the technology to media companies who wished to have their media playable on the iPod or Apple TV, with the protection of FairPlay DRM, but without having to go through Apple.

"I just want to say what I great product you have. I was reluctant to install it after trying 3 applications before that did not work. This product is excellent. The only thing I had trouble figuring out was that I have to have the M4P Converter loaded AND iTunes at the same time. Once I figured that out, I fell in love in what this product does."
