How to delete/remove Aps from iPhone or iPad

Touch and hold any app until all the apps start to jiggle. In this mode you can delete apps by touching the x that appears to the upper left of each app, except the apple no delectable ones. You can also move apps around by dragging them to new positions. To get out of this mode press the home button once.

If you sync via iTunes, you can also delete apps that way.

You tap on a App for a few seconds and than tap The "x" Butten and it's removed!
