Ipod touch 3rd generation calendar sync problems.

Question

I have just updated my IPod Touch 3G to Software version 5.1.1.
The calendar has been synced and all entries, including those in Outlook itself, not just the IPod, have been erased from 12 months ago.
The calendar sync is to Outlook. Fortunately this is a repeat performance and I have learned to keep a backup of calendar entries as a .pst file. Therefore all that was needed  was to resync the system to the. pst file.
There is however, another observation. After a resync, all calendar entries from year 2000 (in my case) can be listed on the IPod. Past experience has shown that after a few days, involving another sync, all entries before 12 months ago will not list on the IPod.
The calendar entries are there, shown as dots against the date, but they will not list on the IPod.
Also the IPod search feature will only search entries for the past 12 months. This is to be expected, since the IPod processing features can only be limited, due to indexing etc. You can't expect the IPod to perform the same as a larger PC.
Does anyone have this problem?
I keep a backup pdf file of the calendar on the IPod and PC, but even then the search on the IPod pdf file is limited to letters only, not numbers - again probably due to indexing problems.

First, try a system reset.  It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until you see the Apple logo.  Ignore the "Slide to power off" text if it appears.  You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore.  Note that it's nowhere near as quick as a Reset.  It could take well over an hour!  Connect via cable to the computer that you use for sync.  From iTunes, select the iPad/iPod and then select the Summary tab.  Follow directions for Restore and be sure to say "yes" to the backup.  You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod.  Again, say "yes."
At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod.  As before, say "yes."  Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time.  If that happens, only the apps that are part of the IOS will appear on your device.  Corrective action is simple -  choose manual "Sync" from the bottom right of iTunes.
If you're unable to do the Restore, go into Recovery Mode per the instructions here.
