I recently ripped some of my vinyls to .aiff lossless, and I have been having trouble getting them onto my iPhone 4. The bitrate is around 4,100 kb/s, and while the tracks appear in iTunes, they don't sync to my iPhone. It is not the file format, as I have previously synced .aiff songs to my iPhone. There is no notification or anything. Is this a limitation of the iPhone? Is there something I can do to retain my music's original quality and get it onto my phone? Thanks.
