So I don't know if someone already said this because quiet frankly I don't feel like searching through 6 pages of "I don't know but I would like to" and "Apple needs to do so & so".. Here's an HELPFUL answer. You can't permenatly delete apps, but you CAN hide them.
1.Go to iTunes, click "iTunes Store".
2.At the top click "App Store", and once it loads, scrol all the way down to the bottom where there are a bunch of links.
3.Click "Purchased" under "Features".
4.Once the Purchased page comes up, Click "Apps".
5.Then find the apps that you want to hide, and put your cursor over the icon and an X will show up at the top left... CLICK.
And you're done.
