    I tunes 9.2.1(5) will not back up my 3GS with 4.0.1 on it. I keep getting

    "iTunes could not back up the iphone … because a session could not be started with the iPhone."

    I tried fixing permissions, rebooting, etc and so on.

    Anyone else having this issue?

    Thanks

    Have you tried giving them privacy?


    I have no idea why it's doing this. Did you update to 4.0.1 from 4.0 or 3.1.3?

    A joke that must not have made it.

    Have you tried restarting the iPhone and your Mac? Also try manually changing time on both, then allowing them to automatically adjust the time over the Internet.

    Haha, I got the joke right after I hit the reply button.

    I tried what you said with no success.

    I'm not sure then. When did the last complete backup preform correctly? Have you done anything new or different to your iPhone within that time frame?

    I had this problem when I put a prerelease copy of iOS 4.0 on my wife's 3GS using a prerelease copy of iTunes. Now, weeks later, both her iTunes and her iPhone are at the latest official version but she still has the problem and I never found an answer. I am a bad husband. I was planning to do a clean restore of her iPhone and see if that helped.

    I can't even manually back up the phone. I was going to try and restore but I would lose a ton of new contacts and info.

    We could ask the bed if that's true.

    If it syncs your contacts and calendars. You won't lose that. You will lose all texts, settings, and app data that has changed from the last backup that worked.

    Or bump. :)


    Found this solution from Apple:

    1) Go to iTunes>Preferences>Devices
    2) In the "Device Backups" window select your last backup on that device. If you have other iPhones they will show up as well...so choose the device your having issues with.
    3) When you've selected the correct device and the last backup the button that says "Delete Backup" will darken. Click it.
    4) Go thru and say "OK" when prompted.
    5) Go back into your iTunes app window and **right click** on your device that is having back up issues.
    6) In the pop up window choose "Backup".

    If you really don't want to lose your backup in case the above doesn't work, you can make a copy of your backup folder found in /Users/USERNAME/Library/Application Support/MobileSync/Backup and put it in a safe place.

    Another solution is to uninstall and reinstall iTunes.

    Do a DFU restore then. It’s a last resort, but you need to be able to backup. Make sure you sync as much as you can thru iTunes.

    Read the last part of what I wrote “make sure you sync….” If you sync everything you can, then restoring will be relatively painless. If you’re worried about losing music, then use expod, which is free.

    Yes, or if you want the cleanest install possible you could restore in DFU mode (see my sig for a link). Whatever you do, make sure you’ve synced, because after restoring that is the only way to get back your stuff. I also suggest syncing your contacts online as a kind of double protection (I’ve used Funambol, but you can use GMail as well).

    Found a solution without restoring

    Try the apple solution : didn't work.
    On itunes : when clicking on my ipad, summary, options I checked encrypt ipad backup, added a password and could create a back up
    Now it sync/back up without problem.

    Here's What Worked for Me

    I had the same issue. Deleting the backups in iTunes wasn't enough for me. Here's everything I did that worked.

    Go into iTunes, preferences, Devices, delete all the backups.
    Go into Finder, user, Library, Application Support, Mobilesync, backups, delete all the folders in there.
    Empty trash can.
    Restart computer.
    Hard reset iPhone (hold down home button and sleep/wake button for 10-15 seconds)

    You shouldn't lose any data at all with this method. When everything booted up, it backed up with no issues at all.
