How to erase apps in my iphone s4?

I want delate unwanted apps in my iphone s4

When you hit an app icon they start to twiggle and then you can delete it. If you want to permantently delete and app you need to go into itunes and manually delete it.

Hold down any app icon. They will start to wiggle and an x will appear in the corners of apps that can be deleted. Hit that x and it will ask u if you want to delete it.
