Yup - that much I'm sure of.  Apple definitely hasn't adopted apt-x in iOS.  Does anyone know what approximate bitrate we can expect when transmitting lossless files from iOS > m2's via SBC codec?

That's good to know - thanks!   How about from the iPhone itself?  Forgot to mention the files themselves are FLAC/Lossless!
