I got my first iPhone yesterday and since I was at the office at the time, I went into iTunes on the phone and selected Purchases. I then downloaded my purchases to the phone. I noticed that some of the files were smaller than I expected. Once I got home I found that at least one album had been downloaded as 128 kb/s DRM AAC, while the original version on my computer was 256 kb/s DRM-free. Furthermore, after synching I now have both versions on my phone! Has anyone else run into this?
