Tap and hold on an app in the app list. The view switches back to the home screen. At the top of the screen is "View app info" or something like that.

Drag the app onto the "View app info" thing.

A very odd bit of UI, no idea whether that is standard across all version of Android or not.

Edit:

The less odd route to it is:

Settings -> Apps -> All

And then just tap on the app.
