Titanium Pro advises it can convert Cardock to a user app, apparently from a system app? I find Cardock a useless app. Does that mean I can delete it once it is converted?
Not sure. To the best of my understanding if you delete anything (Apps) that come with your phone you will never, ever be able to get any kind of OTA upgrades- such as the new Gingerbread that just came out. If you have Titanium just freeze it. When new updates come out, all you have to do is unfreeze it. When you get the update, freeze it again.
