agnesau Level 1 Level 1
I’m using iPhone 3G. Just restored and upgraded to OS4. All my songs, contacts, calendar could be backup to my iPhone after the upgrade. Then, I downloaded some eBooks with my iPhone. But when I tried to sync the iPhone with iTunes 9.2 one day after the upgrade, no new eBook records shown on iTunes, no calendar updated on Outlook and on photos were sync to iPhone after the backup process. It seems that iTunes only performed backup but no data synchronization was done.

Can anyone help me? I can’t transfer songs, photos to iPhone. Please help. Thanks.

iPhone 3G, Windows 7, n/a

    I have a similar, but slightly different issue. Also on an iPhone 3G. Some of my stuff synced, but not all of it. I've got my apps, my contacts, calendar, eBooks, and my pictures, but not my TV shows, movies, music, etc. And when I try to add them back into iTunes (File: Add file to Library), then select them to sync by selecting my iPhone under Devices in iTunes and clicking the Sync Movies box, then selecting the movies I want to sync, and clicking Apply... it says, "The iPhone "My iPhone" is synced with another iTunes Libary. Do you want to erase this iPhone and sync with this iTunes Library?"

    I don't! And my iPhone is not synced with another iTunes Libary. What can I do?

    Couple of things... do a hard reset on your phone. While that's underway, close iTunes down and reboot the PC. After the PC is back up and the iPhone has restarted try the sync again and see if this helps.

    Nope, did all that, and still cannot sync my movies, music, etc. I get the same error message as before.

    I'm tempted to just say "Yes" and tell it to erase everything and sync to the "new" (NOT) iTunes Library. But I'm afraid if I do that, I will lose my data (calendar, pictures, contacts, etc...)???

    another strange is that, i've grouped some apps on iPhone and iTunes shows the apps are in groups after sync. that means iTunes sync some data but not for some.

    I'm having similar issues.

    My phone will sync music, but no TV Shows or Movies. I even tried to manually manage the files, I drop the files onto the phone and nothing happens!

    also, without saying, the phone is slower.

    I tried sync for many times and noticed that the iPhone restarted automatically during the backup process and the backup process has been forced to be terminated. After restarting the iPhone, the sync process halted. Basically, the backup and sync process couldn't finish.

    Seems like lots of syncing problems. And when I tried to contact Apple, it says my iPhone is out of warranty, hence my presence here. Seems like Apple would support this OS upgrade?? Thanks to dmiannay for at least trying to help. Anyone here have any other advice?

    I thought the same thing, as I had this issue too. I went ahead and let it erase and sync, making sure I had everything checked off that I wanted it to sync....my specific ringtones, movies, music, contacts, apps, etc....and it went through the sync no problem. You don't lose anything....it basically is just 're-syncing'. After that everything is peachy. I guess when you update itunes, it loses the info that associates your devices to itunes, but all backups are still in tact.

    Thank you EricandJulie! Got it all working now!

    I installed os4 on my 3G 2 days ago and have lost all my music and purchased apps. The icons are still there but the apps close 2 seconds after opening. I've restored my phone and tried to re sync the apps and music. The apps seem to be copied but audio content throws up errors and on occasion itunes says it can't find the files. At one point it said the phone was synced to another library. It may be a coincidence but at the same time my gmail password was changed and I had to reset it on my computer too. Deep joy. Is there anyway to revert to os3? Roll on os4.1!

    I tried EricandJulie!'s method and still no use. I will restore the iPhone to factory setting again and restore the data. See if it works.

    Okay - So here's what worked for me

    unchecked the sync Ringtones
    Sync - confirm that you want to remove ringtones from the phone

    Check the Sync selected ringtones and selected one
    Sync - Sure enough the sync dialog showed that it was syncing the ringtone I had selected.

    Checked the Select all ringtones
    Sync - All Ringtones back on my phone

    NOTE:
    I did all this without discobbecting or reconnecting the iPhone
    I am Using latest itunes and Snow Leopard
    I have iPhone 3GS

    After restored the OS to iPhone, I can sync all apps, songs and calendar to iPhone. But when I unplug the iPhone and plug it again, the iTunes starts backup process and problem occurs again. During the backup process, the iPhone restarts. As the backup process doesn't finish, the sync process doesn't start. I can't sync songs, apps and calendar to iPhone again.

    It seems that it is the problem of backup. Do you know how to bypass the backup process and let iTunes syncs iPhone?
