However, the X8 does have the "infinity button" in the media player. Tap it while a song is playing and it searches for related videos on YouTube and MP3s for sale in Sony's PlayNow music store.Isn't it great!
I don't et it why you need to do that. maybe to listen through bt and control from this? well the default music app automatically allows headset to have control, as long as winamp asks settings.
to send files to another gadget just use a file explorer like es explorer.
