1. What file formats, in addition to MP3, does it support?.
2. If it supports additional formats is there a limit to the support, such as not playing anything ripped at 160 kbps stereo but playing it if it had been ripped at 128 kbps stereo? This question also applies to MP3 support.
I'm getting a microSD card ready for my wife and don't have the phone in hand to test what it supports. Putting together the tunes for the card is going to take some time so I want to get started but do not want to fill it up with songs the phone won't play.
