On my iPhone, I go to the App Store. I download some app. It's crap, so I delete it, by clicking the 'x' when the icons start wobbling.
Some time later, I turn on my mac, and iTunes starts syncing with my iPhone. For some reason, iTunes copies the APP I DELETED over to my iPhone, so I have to delete it again. Only when I delete it again will it stop copying it.
I find it hard to believe this is a design decision. It would be understandable to keep the app on my computer, but why does it copy it over to my iPhone even though I deleted it there?
Specs: latest version of iTunes on latest version of Lion, and latest version of iOS on iPhone 4.
