how do i delete apps on itunes ??? i went to the library and it only shows a few apps that i have. But when i go into my account i can see all of the apps i have downloaded. soooo how do i delete the apps that are only showing in my account?

No you can't. Apple is keeping it for account purposes, so if you change your mind, you can download it again for free.

If you plug in your iphone, click on it in iTunes, and go to the apps section, it should be checked to sync apps if you want them to show up in iTunes as well as your iPhone. Once synced they will show on both.

Then if you click Apps under the Library header in the left panel of iTunes, you'll be able to permanently delete apps, removing them entirely from iTunes. Highlight an app's icon or a group of icons by holding down Shift and hit the delete key (or select Edit > Delete from the top menu or right-click on an icon and selecting delete).

You can only delete apps locally from your harddrive, you can't delete it under purchased.

Had the same query and followed "BriGuy419" advice. It worked. (You can't delete it in purchased, but if you go to library header in the LHS pane of iTunes and delete an app, it also deletes it in purchased.)
