I get this when trying to update my iPhone: "could not be synced because the sync session failed to finish." Have lost many apps and date. Hope it's not permanent.

Help?

I know you said everything is up to date, but just to make sure....iTunes is at least 10.5, right?
Have you tried resetting sync history? (Edit>Preferences>Device>Reset Sync History: It won't delete any of your information)
Also, you can run a iTunes diagnostics test just to make sure everything passes.
I would also try to backup your back up files on an external drive (http://support.apple.com/kb/ts2529) and delete the backups in your system, to see if anything in there was stopping the syncs from going through?

I keep getting this when trying to open Time machine: An unexpected error occurred (error code -6584). time machine wont even open up. My Time capsule has a green lite and appears fine
Thaks,

This often means the backup is corrupted.
First of all reboot the network.. turn everything off and restart in order.. modem.. TC.. clients.
If you still have issues, hold the option key when you click the Time Machine icon on the top menu and it will bring up verify backups.
Do that.

Errors related to downgrading iOS
The required resource cannot be found: This alert message occurs when your device has a newer version of iOS than what is available in iTunes. When troubleshooting a device that presents this alert message, go toSettings > General > About and check the version of iOS on the device. If it is newer than the latest released iOS version, the device may have a prerelease developer version of iOS installed. Installing an older version of iOS over a newer version is not supported.
Error 1015: This error is typically caused by attempts to downgrade the iPhone, iPad, or iPod touch's software. This can occur when you attempt to restore using an older .ipsw file. Downgrading to a previous version is not supported. To resolve this issue, attempt to restore with the latest iPhone, iPad, or iPod touch software available from Apple. This error can also occur when an unauthorized modification of the iOS has occurred and you are now trying to restore to an authorized, default state.
There is not much you can do, sorry

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.....
