When you got a Galax Nexus Verizon version, you will find there some system apps that you would never use. If I were you, I will move heaven and earth to delete them all. But as we know, in the previous version of Android, you need to root your mobile phone and get the top authority to delete the system apps. Right now, it becomes different.

Thanks to Ice Cream Sandwich, though, it's easy to get Verizon's intrusions out of sight and out of mind. Ice Cream Sandwich includes a new feature that allows you to disable and hide any system app. The app won't be fully removed from your phone's storage, but it'll never run -- and you'll never see it again.
However, this kind function isn’t limited to Verizon Galaxy Nexus, it will also come to more and more non-Nexus devices. If you get the Android 4.0 Ice Cream Sandwich, and want to disable some annoy system apps, please check the next 4 steps.

They're really quite simple:

1. Go into the main system settings. (You can get there by selecting the "Settings" icon within your phone's app tray.)

2. Scroll down to the "Device" section and select the "Apps" option.

3. Tap the tab at the top that's labeled "All," then scroll through the list to find the app you wants to blast.

4. Tap on the app, then tap the "Disable" button. Tap "OK" on the confirmation box that appears.

After those steps, you can successfully disable the system apps. If nothing happen, just restart your phone.
