Yes but if you go into music/itunes and back-up the itunes folder onto a USB stick or something then put it back on your computer once you reinstalled itunes then it should be fine.

First try turning your device off and turning it back on.

If that doesn't work try resyncing the iPod through iTunes. This should fix the problem.

If not, try restoring to a previous backup when your applications did show up.

If this either doesn't work or you don't have a backup to restore to the only option may be to reset your device by restoring it to it's factory settings.

If your apps are still not showing up after doing a factory reset you may need to contact Apple for further assistance.

To delete photos from iPod touch:

In iTunes, select the device icon in the Devices list on the left. Click the Photos tab in the resulting window.

Choose "Sync photos from."

On a Mac, choose iPhoto or Aperture from the pop-up menu.

On a Windows PC, choose Photoshop Album or Photoshop Elements from the pop-up menu.

Choose "Selected albums" and deselect the albums or collections you want to delete.

Click Apply.
