Difference between contentWidth, logicalWidth, deviceWidth ?

Hi all,
was hoping someone could someone confirm if I understand the difference between the three.
contentWidth: takes into account the orientation of the device when returning the width in pixels (eg on an iPhone 3GS in portrait it will return 320 but in landscape will return 480)
deviceWidth: returns the width in pixels (eg on an iPhone 3GS it will return 320 regardless of if you're in portrait or landscape)
logicalWidth: ignores the device and just returns whatever you've set in the "Logical dimensions" in the project properties.
I'm assuming Gideros uses the Logical dimensions in conjunction with the Scale Mode to magically re-format for different sized displays, so if that's right, when would you actually use logicalWidth/logicalHeight in your code?

In 2011.9 API docs there are only methods:
Application:getLogicalWidth
Application:getLogicalHeight
Application:getDeviceWidth
Application:getDeviceHeight
The other betas are here:

I'm not sure why they are not listed on the Download page.
So does contentWidth and contentHeight really return incorrect sizes (does they match logical sizes that were set)?
What are your device dimensions?
