I wanna delete a bunch of apps i never use off my phone. The catch is they are all in categories and when i click on categories it gives me the "welcome to categories!" message like i just downloaded it. The app is empty, void of my four folders and 200 apps. Can I just sync my phone with my computer after deselecting the apps I no longer want using itunes? I feel like i read somewhere that you have to remove them from the category before you delete or bad things will happen. Thanks!
