If  you have categories on your iphone, you may have noticed that when you update an app, it creates a new icon on the iphone’s ‘desktop’.  The fix? Simply refresh categories.  Here are the steps…

1) Open categories

2) open any folder

3) click add.. You do NOT have to add anything

4) close and hit refresh spring board.

Ta da.  Your extra icon should be gone.
