I've tried Youcast, Hoccer, bluetooth file transfer, androbex and astro bluetooth module and NOTHING works. I've searched and read countless post and NOTHING works. I don't care about sending pics or doc, I want to be able to send full mp3 files without using email. I have a Samsung Moment, 2.1 upgrade and everything is great except I can't send mp3 via bluetooth or text. If someone can help me do this using whatever works, free or paid apps, I'll pay u.
