The preinstalled apps that came on your iPad mini can't be removed, but you have two ways to delete any other app: in iTunes on your computer or directly from your iPad.
You can, however, hide certain preinstalled apps by choosing Settings→General→Restrictions.
To delete an app in iTunes (that is, from your computer), choose Apps from the Library pop-up menu or select Apps in the sidebar and then do one of the following:
Click the app to select it and press the Delete or Backspace key on the keyboard.
Click the app to select it and then choose Edit→Delete.
Right-click the app and choose Delete.
After taking any of the actions in this list, you see a dialog that asks whether you're sure that you want to remove the selected app. If you click the Remove button, the app is removed from your iTunes library as well as from any iPad that syncs with your iTunes Library.
Here's how to delete an app on your iPad:
Press and hold any icon until all the icons begin to wiggle.
Tap the littlexin the upper-left corner of the app that you want to delete.
A dialog appears, informing you that deleting this app also deletes all its data.
Tap the Delete button.
You can't delete any of the bundled apps that came with your iPad.
To stop the icons from wiggling, press the Home or Sleep/Wake button.
You also make icons wiggle to move them around on the screen or move them from page to page. To rearrange wiggling icons, press and drag them one at a time. If you drag an icon to the left or right edge of the screen, it moves to the next or previous Home screen.
You can also drag two additional icons to the Dock (where Safari, Mail, Photos, and Music live) and have a total of six apps available from every Home screen.
Rearranging your icons in iTunes is faster and easier than making them wiggle and move on the iPad.
