Re: iPhone 4 says it's full but it's not - HELP!
What about finding another program that talks to the iPhone and see what that can tell you.
I use one call Media Monkey which talks the iPhone without problems (it's about $20 for the gold version which includes ripping to Mp3 - the free version is slower ripping to all formats but MP3).
