This is my solution to "Syncing User's iPhone" continuous sync problem.
1. Plug iPhone to iTunes
2. Cancel sync immediately.
3. Uncheck sync contact in iTunes.
4. Uncheck sync music. (Remove all songs)
5. Create a playlist. (e.g. test playlist)
6. Put 1 song into the playlist.
7. Sync the 'test playlist'
8. Wait for sync to complete. (It should complete within 15 minutes)
9. Uncheck 'test playlist', check the songs you want to sync.
10. Hit sync and wait.
11. I waited my iPhone to sync for around 40 minutes. (just wait, it should work.)
12. Done! ;D
