deleting apps from my itunes without deleting them from my iphone

[krystalstaarr]

Hi! So I wanted to know if there was a way to delete all of my apps from my itunes but still keep them on my iphone. When i try to click off the sync button off the application tab, it says that all my apps would be deleted off my iphone. I love my apps but i don't want them on my computer, having only one gig left on my computer hard drive. Is there a way to get them off my computer without deleting them from my phone, kind of like when i manually sync my music on my ipod. I can delete them from the itunes, but they stay on the ipod. Thanks any help would be amazing!!!!
