Ive been looking around the net for the last two days, and have seen alot of people with the same problem, but no answers. So Im wondering what the problem is.

Just got my iphone 3g a few days ago, synced my bookmarks, apps, ringtones just fine, but when it gets to music it quickly stops and shows the apple logo. Now I have alot of music so I decided to only sync a few playlists that i have on my zune, which I converted to wpl, then to m3u(the playlist itunes recognizes). Now 3 out of four playlists I added show up on itunes, but they just wont sync to my iphone. This is infuriating.

Also, I have a ton of space on my iphone so thats not the problem.
