I'm glad you found it helpful.
I've had good success with wav as well on my cell phone which has windows media player. Although I forgot to mention above, that just because a mp3 player states that it plays wav, doesn't mean it can play lossless wav files. That was were I made my mistake with my first player which could play wav (and recorded to wav), but couldn't play lossless wav files which play at at kbps rate that was too high for the player.
