my iPod Touch 4G has stucked while syncing with iTunes on MacMini. I slided to cancel the sync and "Canceling sync" remained on the screen. It was possible to open some apps, but Music could not be opened. I tried to restart the iPod and now it just show Apple logo and stucked progress bar. It cannot be rebooted. It only connects with iPhoto and it is possible to import images. It is trying to connect with iTunes but the progress bar is turning around but no content appears.

Is there a way to fix this? Thanks for help Beek
