Many users of an iPhone with Jailbreak are experiencing problems when syncing with itunes 10 applications. Below I leave some simple steps to fix the problem:
The error is due to a library that is automatically installed from Cydia called "IconSupport" which is used, for example, Infinidock, Infinifolders or Infiniboard.
To prevent iTunes sync not we just turn IconSupport before connecting the device.
Steps:
Free Download SBSettings from Cydia located in the BigBoss repository.
After installation we open SBSettings sliding your finger on the status bar in the same way to unlock and press on "More".
Select "Mobile Sustrate Addons".
At this point only disable "IconSupport", press the "Home" button to exit and an automatic respring was made.
At the end we can connect the device to your Mac or PC and sync.
After synchronization we can reactivate "IconSupport"
