Is there a specific list for ICS ROM? I wonder if it would be different than the old GB freeze list.
If so, does anyone have a starting point for ICS bloat freeze?
Yes, you will need root.
To freeze the apps, you need to get the Titanium Backup app in the market. (It's one of those must have tools.) Besides backing up (obviously) you can click on a specific app to get a menu. This menu will have the freeze option. Note that you don't want the long press menu if you just want to freeze an app. Long press brings up a different menu.
