    Got a new iphone 4. The first sync I did last week worked great. Everything was up to date. Plugged the phone back into itunes today and now it's stuck on "backing up" or "syncing". Most of the time, itunes just freezes. Other times an error pops up saying there is a communication error. Help, what's going on?

    I'm on a 3 year old macbook. Can't recall the error code. The only files that are new are a few (5) apps and contact lists. No huge files. I left the iphone plugged into itunes all night long and the status bar for backing up did not budge. The iphone icon appears on the left side of itunes, the syncing circle symbol rotates, the iphone says syncing in progress; but itunes freezes. After waiting a few minutes I have to force quit itunes. Hope that helps.

    Thanks for the info and help. I'll look into this when later tonight and try to get an error code.
    Ya, it's itunes that freezes while syncing. The iphone is not affected. I'm running the latest version 10.6.4.

    Reset your iPhone

    I had a similar issue with my iPhone but was able to correct it by resetting it. To do that go to Settings->General->Reset->Reset All Settings

    After that I was able to successfully sync.

    Hope that helps.

    :)

    Hi! I'm having problems syncing my iPhone 4 with iTunes as well. I saw the last post about "Reset All Settings" but I was worried that it would delete data on the phone. Here my problem:

    Tried syncing last night on 10.5.8 Mac Pro with iTunes 9.2. This was my first time syncing and I only have about 330MBs used on the phone. I just wanted to sync my contacts to the computer basically so only the "Info" tab in iTunes was checked. The phone tried to backup but it didn't look like it was doing anything. (Waited 10-15 mins). Canceled the sync, which froze iTunes (had to force quit). Tried restarting the computer, tried turning off "auto-sync when device is connected", tried only syncing my calendar (since there is less data on there then the contacts. Nothing is working. Every time it just goes to backup the device and stops.

    I'm trying it now on a 10.6.4 iMac (obviously a different computer). The "backup" has been running for an hour with no movement. Thoughts? Any help is appreciated! Thanks!!!

    Fixed!

    Hey all,

    Hopefully this might help someone else out, but after 2 hours of iTunes saying "Backup iPhone" I decided to cancel the sync. I unplugged my iPhone and turned it off (holding the top and home key at the same time). Restarted it up and plugged it in. Went to sync and the backup was done in seconds!

    So, I guess the moral of the story is don't forget to try restarting the phone. :)

    Thanks for the tip

    I had this problem recently as well and I wanted to share how I fixed it so that should it happen to anyone else they won't have to pull their hair out.

    The other day I installed X11 (if you don't know what it is, don't worry) from the Snow Leopard DVD and then my iTunes would not see my iPhone 4 any more.

    I tried rebooting the phone, that didn't work.
    I tried restarting the computer, that didn't work.
    I tried seeing if it would show up on another User profile, that didn't work.

    What worked? Reinstalling iTunes.

    By the time the installation was complete, my iPhone automatically made a noise as if to say "I'm syncing again!" And then everything worked.

    iphone 4 syncing problems

    My iphone 4 suddenly was becoming stuck during syncing (on Contacts or Calendars).

    Eventually I found help in this article:

    http://support.apple.com/kb/TS1627

    which told me to reset the sync services folder by going into the terminal app and typing

    /System/Library/Frameworks/SyncServices.framework/Versions/A/Resources/resetsync.pl reset

    Read the article for complete instructions.

    Reset All Settings worked for me

    New G4 wouldn't connect to itunes and sync upload my previous phone's apps and data. The advice above to use Reset worked for me. Thanks :)

    My Iphone Won't Sync Still

    I have had my iPhone 4 for one week. It would sync with no problem until today. I have a Windows PC and the latest version of iTunes on it. It will go through all 4 stages of the sync process and at #4, a window pops up and says, "iTunes could not backup the iPhone ___ because an error occurred."

    I have gone through this thread and tried every option given. It is still not working.

    Any help?

    my iPhone 4 won't sync with my iTunes on my MacBook Pro

    I am getting an error message that my iPhone won't sync because the required disk could not be found. When I close that, then I get an error message 0xE8000001. Anybody have any idea what to do to fix this? This used to happen with my previous iPhone too. I don't expect this with my Mac.

    I'm finding the whole iPhone 4/iTunes nexus shockingly badly engineered. Indeed, it's offered me a window (so to speak) into the entire Mac OS environment (I recently migrated from Windows to Mac on the basis of my positive experience with my iPhone 3g) that's been quite a surprise.

    Contrary to my expectation, I've found the Mac OS environment to be :

    a) cumbersome and rigid
    b) buggy (crashes far more than Windows 7)
    c) and, of course, expensive

    I'll be returning to Windows, and ditching my iPhone for Android, poste haste ...

    Okay, and what iPhone model + iOS are you using?
