To completely remove iPhone apps, you must find the application that you would like to delete. Touch and hold down on the application for a few seconds. The screen should start to wiggle and an “X” will appear on the upper left corner of each application icon you’ve installed. Touch the “X” of the app you want to delete. Select “Delete” on confirmation. You also will be alerted that the data will also loss when an app is deleted.
However, there are some apps that are undeletable. Some of them are Notes, Safari, Stocks and Maps. These are preloaded apps that came installed on your phone. No one can delete them. One more thing: before deleting these iPhone apps, you have to be sure that you really want them vanish from your display. You had made a pretty expense for them, hadn’t you?***
