Iphone could not sync

Most of the time when I connect my iphone to itunes on my imac it says it cannot sync because it cannot establish a connection with the iphone. If I go to sync it manually it syncs ok. Is this a common problem? I have the latest versions of iphone os 3.1.2 and itunes 9.0.2. It has only started doing this in the last few weeks.

I just recently started experiencing the exact same issue. The only thing I've changed with my setup is I added a 4-digit security PIN to the phone. I'm using Windows XP-SP3 as my OS, so it's very possible that Microsoft pushed an update that is causing the problem, but I notice that you're on a iMac. I haven't sat down and conducted any serious troubleshooting yet, but thought I'd add a post to the thread to give it a little help. I'll post some results after I try a few possible solutions and test them by connecting/disconnecting about 10 times for each (disable the security PIN, uninstall recent OS fixes (if possible), etc.).

TS4062 I am getting error msg when trying to sync-iPhone could not sync because the sync session failed

I am trying to sync my iPhone and receiving the following message: iPhone could not sync because the sync session failed
I have tried walking through the set ups again, and cannot figure this out. Any help out there? Thank you.

I seemed to have figured it out...... I hard reset my Iphone and rebooted my computer and it seemed to work. It also seemed there was a music file that was not being recognized, I just erased it and everything worked fine after that.... very strange but I am so glad I figured it out.....

IPhone could not sync because the iPhone is disconnected

I have downloaded iTunes 8, but when syncing my phone and trying to download the newest iPhone software (2.1), I keeep getting an error message that reads as follows:
"iTunes could not sync ^0 to the iPhone "xxxx's iPhone" because the iPhone is disconnected".....when it is indeed NOT disconnected. Any ideas or fixes? The new iPhone software has been downloaded on iTunes, but not yet downloaded to my phone due to the aforementioned error message.

I am having a similar problem since going to iPhone 2.1 and iTunes 8.0. My iPhone sees my computer, and my computer sees it, but iTunes does not launch or see my iPhone, so I can no longer sync (running Vista, btw). Would be grateful for suggestions.

Make sure you don't have Restrictions enabled under Settings/General. If it's enabled, you might need to restart your phone afterwards.

Syncing photos via iTunes - getting new error message" "the iphone could not be synced because the connection to iphone was lost"

I am trying to sync photos in a dedicated file on my desktop with the photo library on my iPhone 4S. Something I have done many times before.
Since upgrading to iTunes 11 I get this message "the iphone could not be synced because the connection to iphone was lost" midway through the sync. I do not understand this as I am syncing via the USB lead, so how can the connection be lost?
Bascially I just want to update the photos on my iPhone with new photos I have added to the file I use on my computer.
Any help or ideas would be gratefully received. Thanks.

This may help you

This iphone could not be synced because this computer is no longer authorised but i try again and it says already authorised

I am trying to sync my iphone 4 to my computer ( Windows 7 64 bit ) so I can update my apps. when I connect my phone to the computer, a window pos up with the following . . . . . . . . .
this iphone 'colin's iphone' could not be synced because this computer is no longer authorised for purchased items that are on this phone
to authorise this computer for items purchased from the itunes store, choose store > authorise this computer OK.
I click on Store, authorise... type in apple id... type in password... click on authorise
It then says.... this computer is already authorised.... including this one, you have authorised one computer out of your available 5.
I unplug my phone and plug it in again and it does exactly the same again???
I'm just going around in circles???

I found the solution to this problem
the apple service helped me actually
the best and the esiest way is to solve this problem :
create a new account (as an administator recomended)
Bonjour servises must be enabled ( go to control panel > administartive tools> sevices> Bounjour services (change the category to large icons if you dont see administartive tools )
install itunes
sign in
authorize
SYNC
it must sync normally
but if the meesage pops up that points on a particular items that could not be synced ( to ur itunes because you are not authorized for this items ) REMOVE THEM
creating a new user account shows the items wich dont let you sync your iPhone
after you REMOVE those **** items that were not authorised , you can go to your old user account and SYNC it as old kind time
was having this problem 2 weeks , and nothing helped except this was. not deleting the SC Info folder, now copying apple folder to some other mobile divce folder
REMEMBER the problem is in your iPhone , it is about the items that are in your iPhone
Thanks to Apple service
for anyone who needs othe heple you r welcome to ask
will hepl you with a pleassure cause i know how I felt this days:)

The iPhone could not be synced because this computer is no longer...

This is not about wanting to manage music, etc. It's about my work. I have an app in development and need to load the latest IPA for testing, a process performed through iTunes, like syncing anything else. When I try and sync I get the message, "The iPhone could not be synced because this computer is no longer authorized for purchased items that are on this iPhone.
I did the research on the internet and haven't found an adequate answer. I've tried:
— Being sure I'm logged into the same iTunes account as the iPhone.
— Deauthorizing then Authorizing the computer, after which I get an alert saying the computer has been successfully authorized, resulting in the same error message again when I again try and sync.
— Removing the SC Info folder, as found in this article: http://support.apple.com/kb/TS1389 . I guess I have the only Mac that has no trace af any such "SC Info" folder anywhere in the system (OS 10.6.8).
— Logged in under every conceivable account configuration (computer admin, device account, etc...) to no avail.
I have to get this IPA imported into the iPhone. It's the same process as syncing anything else. If anyone has a solution, please send it along. Clock is loudly ticking.
Many thanks.
Cayce

Same problem. Did you guys find the solution?

The iphone could not be synced because this computer is no longer authorized for purchased items 2014

the iphone could not be synced because this computer is no longer authorized for purchased items

Hello 7283,
Thank you for providing the details of the issue you are experiencing with syncing your iPhone. It sounds like you computer is not authorized for some of the purchases on your iPhone.
I am not sure if you have authorized your computer, but I recommend trying that first. If you have purchases from multiple Apple IDs on your iPhone, you will need to authorize all the Apple IDs used to make purchases. Use these steps:
Open iTunes on the computer you want to authorize.
Choose Store > Authorize This Computer from the menu bar.
You may need to show the menu bar to see this option in Windows. In earlier versions of iTunes, you can access this option from the Advanced menu.
Enter your Apple ID and click Authorize.
Authorize or deauthorize your Mac or PC

If you have already authorized your computer, I recommend reviewing the following article for additional assistance:

HT1727 iphone could not be synced because this computer is no longer authorized for purchased items that are on this iphone

why is itunes saying "iphone could not be synced because this computer is no longer authorized for purchased items that are on this iphone"

I first called apple and they patched me to a technician who ran a test and determined that I had a virus. He gave me some price quotes and who to call. After my conversation with him, which I knew was BS btw, I immediatley called Geek Squad with whom my computer has a warranty through after they installed virus software on my new laptop (4 months old). I had a VERY long online session where they ran several virus test and found nothing. Although I was VERY happy that my computer didn't have a virus, I still had the problem of my itunes not working. After several hours, he made sure that all of my apps were down loaded, and then restored my iphone to factory settings, and sync my device. It worked perfectly and all and I mean ALL 240 apps were downloaded back onto my iphone along with my music and all of my tones. When asked why my itunes was acting in that manner the answer that I got was,"...apparently you had a correct file some where in itunes and everything had to be reset". Regardless, everything is back to normal and I don't have to get a new phone or delete itunes from my computer. Hope this helps!
