Well, WMA is a Microsoft thing. So it's doubtful.
The top link in http://www.google.com/search?q=wma+android has one program. The next hits seem to be questions and discussions. Better have a look.
Could be some member already has something on their phone and responds more positively.
I want to know if there is anything that can play wma files on a android phone. I currently have crickets zio phone with 1.6.
Thank you, Mega
