Simple way to see a list of installed iOS apps with their storage space size? The storage on my iPhone is nearly full. Most of the space is used by apps. I'd like to see which apps consume the most space on my device.

Is there a way to get a list of the apps with their corresponding used space? By "used space I mean the installation size (bonus for added user data).
iOS 5 has now introduced a new feature under Settings > General > Usage that perfectly displays the amount of data taken up by every app on the device, sorted by top offenders.
