I have the iPhone 4.. it's a great phone. I love it. I'm having difficulty though syncing all my music to it. I have 385 songs in a playlist that I sync to my phone.. I do the Sync Music - Selected Playlists - Laura's Playlist. That is the ONLY checked option on the entire Music page. However, I only have 334 songs on my iPhone after syncing. I don't have all the artists, even if I select them in the "Artists" box. What's going on? It's really frustrating.
