I noticed that when you upgrade the software via PC Suite, it will check that all pre-installed apps are present before it will proceed. Even the ones I froze using Titanium backup I have to unfreeze them before PC Suite will proceed with the software upgrade. So I am guessing that if you do this, you can kiss goodbye to ever upgrading your software.
