I'm beginning to think that iTunes WiFi Sync doesn't back up the data your phone (settings, app data, camera roll, contacts). It only syncs your music, videos, podcasts, books, etc. from iTunes. Anyone else using iTunes WiFi Sync notice that where it says "Last Backup" on the Summary tab is actually the time and date of the last time you plugged in your phone? I was hoping that iTunes WiFi Sync was the 100% equivalent of plugging your phone into the computer via USB but I'm not so sure anymore. Here's what I think so far: - iTunes Sync via USB will do a contents sync and phone data backup. - iTunes WiFi Sync will only do a contents sync. - iCloud Backup will only do a phone data backup.
